Factoring that out makes it easier to see that you need factors of 12 that add to give 7. Those are not hard to find as being 3 and 4. These numbers go into the binomial factors to give ...

... 4x^2 +28x +48 = 4(x^2 +7x +12) = 4(x +3)(x +4)

Answer:

[tex]4x^2 + 28x +48 = 4(x+4)(x+3)[/tex]

Step-by-step explanation:

We are given the following information in the equation:

[tex]4x^2 + 28x +48[/tex]

We have to factorize the given expression.

We will use the technique of splitting the middle term to factorize.

Factorization can be done in the following manner:

[tex]4x^2 + 28x +48\\\Rightarrow 4(x^2 + 7x + 12)\\\Rightarrow 4(x^2 + 4x + 3x + 12)\\\Rightarrow 4[x(x+4)+3(x+4)]\\\Rightarrow 4(x+3)(x+4)[/tex]

Hence, the given expression can be factorized as:

[tex]4x^2 + 28x +48 = 4(x+4)(x+3)[/tex]

Answer:

Hey!

Your answer is £2121.80 in the account!

Step-by-step explanation:

So to do this, you have to first find out how much would be left after 1 year...

=     3 / 100 x 2000 = £60 *we now add this on to the £2000*

=     2000 + 60 = £2060 *this is what is in the account after 1 YEAR*

Then, find out the amount for the second year!

=     3 / 100 x 2060 = £61.80 *we now add this on to the £2060*

=     2060 + 61.80 = £2121.80 *this is what is in the account after 2 YEARS*

SO AFTER 2 YEARS, THERE IS AN AMOUNT OF £2121.80 IN THE BANK ACCOUNT!

Answer:

5feet per year

Step-by-step explanation:

We need to find the distance it grew in that 7 1/2 years:

63 - 25 1/2 = 37 1/2

Now to find the average yearly growth we can divide this by 7 1/2:

37.5 ÷ 7.5 = 5

So the yearly rate of growth of the tree is 5f/y

Answer:

x = 7.5

Step-by-step explanation:

4 = 2/3 (2x - 9)

4 = 4/3x - 6

4 + 6 = 4/3x - 6 + 6

10 = 4/3x

10 x 3/4 = x

x = 7.5

Lyla needs 5 seed packets to grow a total of 40 flowers, assuming the relationship between flowers and seed packets is directly proportional.

Lyla grew 16 flowers with 2 seed packets. To find out how many seed packets Lyla needs to grow a total of 40 flowers, assuming the relationship is directly proportional, we set up a proportion. We have the ratio of flowers to seed packets, which is 16 flowers for 2 seed packets. We need to find how many seed packets would be needed for 40 flowers.

First, write the proportion:

\(\frac{16 \text{ flowers}}{2 \text{ seed packets}} = \frac{40 \text{ flowers}}{x \text{ seed packets}}\)

Solve for \(x\):

\(\frac{16}{2} = \frac{40}{x}\)

\(8 = \frac{40}{x}\)

Multiply both sides by \(x\) and divide both sides by 8 to find the value of \(x\):

\(x \cdot 8 = 40\)

\(x = \frac{40}{8}\)

\(x = 5\)

Therefore, Lyla needs 5 seed packets to grow 40 flowers.

Final answer:

To find 3/4 of 12, you multiply 12 by the fraction 3/4. Multiplying 0.75 (the decimal equivalent of 3/4) by 12 results in 9. Hence, 3/4 of 12 is 9.

Explanation:

To solve the problem: "What is 3/4 of 12," you would multiply. This type of problem is asking for a part of a whole, where 'of' typically signifies multiplication in mathematics. We can think about this conceptually: if half of 12 is 6, then three-quarters would be half of 12 plus half of 6. In mathematical terms, you would calculate 3/4 × 12 to find the answer.

To break it down:

Convert 3/4 to a decimal if needed, which is 0.75.

Multiply 0.75 by 12.

The result is 9, so 3/4 of 12 equals 9.

This is because when you are finding a portion of a number, you are determining how many times that portion fits into the whole. So, you're effectively scaling the number 12 by the fraction 3/4, which is accomplished through multiplication.

Hello.

X= −5/14 y

Step 1: Add -15x to both sides.

x−5y+ −15x= 15x+ −15x

−14x−5y=0

Step 2: Add 5y to both sides.

−14x −5y+5y= 0+5y

−14x=5y

Step 3: Divide both sides by -14.

−14x/−14= 5y/−14

x= −5/14 y

Answer:

The standard form of [tex]5.68\times 10^{4}[/tex] is [tex]56800[/tex]

Step-by-step explanation:

We need to write [tex]5.68\times 10^{4}[/tex] in standard form

Re-write [tex]5.68\times 10^{4}[/tex] as,

[tex]5.68\times 10000[/tex]

⇒[tex]56800[/tex]

Therefore, standard form of [tex]5.68\times 10^{4}[/tex] is [tex]56800[/tex]

(5q2 − r2s)(25q^4+5q^2r^2s+1r^4s^2)

To factor the expression, identify the difference of squares in the first part and the sum of cubes in the second part. Apply the relevant factoring formulas to obtain the fully factored form.

To factor the expression[tex](q^2 - r^2s) (q^4 + q^2r^2s + r^4s^2),[/tex] we must first recognize that the second part is a sum of cubes. The formula for factoring a sum of cubes is [tex]a^3 + b^3 = (a + b)(a^2 - ab +b^2)[/tex]. The first part, [tex]q^2 - r^2s,[/tex] can be recognized as the difference of squares, which factors as (q - rs)(q + rs). Therefore, after applying these patterns the factored form of the expression is:

[tex](q - rs)(q + rs)(q^2 + qrs + r^2s^2)[/tex]

Answer:

The reference angle for the angle with measure -pi/4 is the angle pi/4

Step-by-step explanation:

The angle -pi/4 is in clockwise and the angle pi/4 is in counterclockwise

The reference angle for the angle with measure -pi/4 is pi/4.

The reference angle for the angle with measure -π/4 is π/4.

A reference angle is the positive acute angle between the terminal side of the given angle and the x-axis in standard position.

In this case, the given angle is in the third quadrant, and its reference angle is the positive acute angle formed by the terminal side of the angle and the negative x-axis. Since the third quadrant is 180 degrees away from the positive x-axis, the reference angle is π/4.

Step-by-step explanation:

13x + 5 + 17x - 4.5 + x

NOTE: You can only add/subtract LIKE terms . Here we have  variable terms in x  (13x , 17x and x) and 2 constants ( 5 and 4.5).

Sarah's next line is

18x + 17x - 4.5 + x

This is incorrect . It looks like she  added 13x + 5 and got 18x!! Which is of course wrong because they are NOT LIKE terms. 5 is a constant and 13x is a variable term in x.

The third line is correct:-

35x - 4.5 + x.

She has added the 2 variables 17x and 18x.

Fourth line  is  30.5x + x. She's at it again - Trying to subtract 4.5 from 35x .

Last line 31.5x

She has added  the 2 terms in x correctly, but the final answer is wrong of course due to the earlier errors.

So if it is 2:00pm in South Carolina USA, then it would be 12:00pm in Montana USA.

Answer:1/6

Step-by-step explanation: because there are 6 side to a cube and you can only have a outcome of 1 so therefore, the answer is 1/6

Final answer:

Juan's experience of rolling the number 2 on a six-sided die 4 times deals with the concept of independent events in probability. The probability of getting a 2 on any single roll is 1/6 and to roll a 2 four times consecutively, you multiply the probabilities, resulting in a much smaller overall probability.

Explanation:

The question involves understanding the probability of rolling a certain number on a six-sided die, which is a concept in mathematics. When Juan rolls the six-sided number cube 4 times and gets the result of 2 each time, we are analyzing a sequence of independent events in probability. Since each roll of the die is independent, the outcome of one roll does not affect the outcome of the next roll and the probability of rolling a 2 on each individual roll remains constant at 1/6.

Event X, described as rolling an even number, has a probability of 3/6 or 1/2, since the even numbers on a die are 2, 4, and 6. However, the probability of rolling multiple 2's in sequence would be the product of probabilities for each roll. That is, the probability of rolling a 2 four times in a row would be (1/6) * (1/6) * (1/6) * (1/6), which is a much smaller probability. This reflects the notion that rolling the same number consecutively multiple times is less likely than rolling it once.

Answer:

Circumcenter =(-1,0)

Orthocenter =(2,-3)

Step-by-step explanation:  

Given : Points A = (2,3), B = (-4,-3), C = (2,-3)  

Formula used :  

→Mid point of two points- [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

→Slope of two points - [tex]\frac{y_2-y_1}{x_2-x_1})[/tex]

→Perpendicular of a line = [tex]\frac{-1}{slope of line})[/tex]

Circumcenter- The point where the perpendicular bisectors of a triangle meets.

Orthocenter-The intersecting point for all the altitudes of the triangle.

To find out the circumcenter we have to solve any two bisector equations.

We solve for line AB and AC

So, mid point of AB =[tex](\frac{2-4}{2},\frac{3-3}{2})=(-1,0)[/tex]

Slope of AB =[tex]\frac{-3-3}{-4-2}=1[/tex]

Slope of the bisector is the negative reciprocal of the given slope.  

So, the slope of the perpendicular bisector = -1  

Equation of AB with slope -1 and the coordinates (-1,0) is,  

(y – 0) = -1(x – (-1))  

y+x=-1………………(1)  

Similarly, for AC  

Mid point of AC = [tex](\frac{2+2}{2},\frac{3-3}{2})=(2,0)[/tex]

Slope of AC = [tex]\frac{-3-3}{2-2}=\frac{-6}{0}[/tex]  

Slope of the bisector is the negative reciprocal of the given slope.  

So, the slope of the perpendicular bisector = 0  

Equation of AC with slope 0 and the coordinates (2,0) is,  

(y – 0) = 0(x – 2)  

y=0 ………………(2)  

By solving equation (1) and (2),  

put y=0 in equation (1)

y+x=-1

0+x=-1

⇒x=-1  

So the circumcenter(P)= (-1,0)

To find the orthocenter we solve the intersections of altitudes.

We solve for line AB and BC

So, mid point of AB =[tex](\frac{2-4}{2},\frac{3-3}{2})=(-1,0)[/tex]

Slope of AB =[tex]\frac{-3-3}{-4-2}=1[/tex]

Slope of the bisector is the negative reciprocal of the given slope.  

So, the slope of CF = -1  

Equation of AB with slope -1 and the coordinates (-1,0) gives equation CF  

(y – 0) = -1(x – (-1))  

y+x=-1………………(3)  

Similarly, mid point of BC =[tex](\frac{-4+2}{2},\frac{-3-3}{2})=(-1,-3)[/tex]

Slope of AB =[tex]\frac{-3+3}{-4-2}=0[/tex]

Slope of the bisector is the negative reciprocal of the given slope.  

So, the slope of AD = 0

Equation of AB with slope 0 and the coordinates (-1,-3) gives equation AD

(y-(-3)) = 0(x – (-1))  

y+3=0

y=-3………………(4)  

Solve equation (3) and (4),

Put y=-3 in equation (3)

y+x=-1

-3+x=-1

x=2

Therefore, orthocenter(O)= (2,-3)

To find the coordinates of the Circumcenter of Triangle ABC, we find the equations of the perpendicular bisectors of two sides and solve them simultaneously. To find the coordinates of the Orthocenter, we find the equations of the altitudes and solve them simultaneously.

The Circumcenter of a triangle is the point of concurrency of the perpendicular bisectors of the triangle's sides. The Orthocenter of a triangle is the point of concurrency of the triangle's altitudes. To find the coordinates of the Circumcenter, we can find the equations of the perpendicular bisectors of two sides of the triangle and solve them simultaneously. To find the coordinates of the Orthocenter, we can find the equations of the altitudes and solve them simultaneously.
