The answer is C because the 2x outside of the brackers must be negative to produce the beginning term. The next terms are positive and two negatives make a positive, therefore we can conclude that there must be a negative inside the brackets too.

Answer: C. −2x(x−3)(x+2)

Step-by-step explanation:

1. Find the Greatest Common Factor (GCF).

GCF=2x

2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2x(2x^3/2x+−2x^2/2x+−12x/2x)

3. Simplify each term in parentheses.

−2x(x^2−x−6)

4. Factor x^2−x−6

−2x(x−3)(x+2)

The answer is C as the net of a cube.

We will select which of four options are the net of a cube.

Remember the net of a cube is composed of six squares.

The answer to this problem is C. Because of the four options, only C has six squares as a condition of a net of cubes.

Following comprises the steps to construct a cube from the net of C:

- - - - - - - - - -

Notes:

Out of the given nets, option C is the net of a cube.

A net of a cube is a two-dimensional shape that can be folded into a three-dimensional figure.

We know that the total number of faces in a cube is 6

So total faces required to make a net of the cube = 6

Options A, B, and D are having 5 faces so they cannot make a net.

So the correct option is option C and we can fold the net to make a cube.

Hence, Out of the given options, option C is the net of a cube.

Step-by-step explanation:

The length has been reduced to 6 inches from 18 inches.

That means the length has been reduced to 6/18 = 1/3 of its original size.

Since -4 is indeed equal to -4, we can say that D, there are many solutions since all real numbers are a solution because any number is equal to itself :)

The equation 5(x-2)+6 = 2x-4+3x has infinitely many solutions.

To solve the equation 5(x-2)+6 = 2x-4+3x, we start by distributing the 5 to the terms inside the parentheses: 5x - 10 + 6 = 2x - 4 + 3x. Next, we combine like terms on both sides of the equation: 5x - 4 = 5x - 4. This simplifies to 0 = 0, which means that both sides of the equation are equal.

Since the equation is true no matter what value of x we choose, this means that the equation has infinitely many solutions.

Answer:

60 cubic feet.

Step-by-step explanation:

The fish are 0.5 per cubic foot. This means 1 fish occupies 2 cubic feet. So if there are 30 fishes then there must be 60 cubic feet.

Answer:Instead of dividing the diameter by two to get the radius, the coworker multiplied the diameter by two, getting a value of 340 feet for the radius. Here’s the incorrect calculation:

volume of a cylinder ≈ 3.14 × (radius)2 × height

= 3.14 × (340 ft)2 × (60 ft)

To find the result of 1/8 - 3/7 - 1/8, we need to find a common denominator for the fractions and then subtract them.

Explanation:

To find the result of 1/8 - 3/7 - 1/8, we need to apply the definition of subtraction and properties of operations. First, let's find a common denominator for the fractions. The common denominator for 8 and 7 is 56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Multiply the numerator and denominator of 3/7 by 8 to get 24/56. Now subtract the fractions: (7/56) - (24/56) = -17/56. Finally, subtract 1/8 from -17/56. Multiply the numerator and denominator of 1/8 by 7 to get 7/56. Subtract the fractions: (-17/56) - (7/56) = -24/56.

Answer:

[tex]y=233\frac{1}{3}[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In this problem we have

For [tex]x=1/4, y=25[/tex]

Find the value of k (constant of proportionality)

[tex]y/x=k[/tex] -----> [tex]k=25/(1/4)=100[/tex]

The linear equation is

[tex]y=100x[/tex]

Find the value of y when the value of [tex]x=2\frac{1}{3}[/tex]

substitute the value of x in the equation but first convert to an improper fraction

[tex]x=2\frac{1}{3}=\frac{2*3+1}{3}=\frac{7}{3}[/tex]

[tex]y=100(\frac{7}{3})=\frac{700}{3}[/tex]

convert the result in mixed number

Answer:

58°

Step-by-step explanation:

If m AM=125°, then m∠AOM=125°.

If m∠MAF=75°, then m∠MOF=150° (because central angle MOF subtends on the same arc as inscribed angle MAF).

Thus,

m∠FOA=360°-150°-125°=85°.

If mEF=31°, then m∠EOF=31° (as central angle subtended on the arc EF).

Hence,

m∠EOA=m∠EOF+m∠FOA=31°+85°=116°.

Angle EOA is central angle subtended on arc EA, angle AME is inscribed angle subtended on arc AE, thus

m∠AME=1/2m∠EOA=58°.

Answer:

260%

Step-by-step explanation:

To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.

1st year = £245

2nd year = £883

First off, we need to find the difference of the two.

Increase = £883 - £245

Increase = £638

Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.

Percentage increase = [tex]\dfrac{638}{245}*100[/tex]

Percentage increase = [tex]2.60*100[/tex]

Percentage increase = 260%

So the percentage increase of last years payment to this years payment is 260%.

Answer:

34.66 yr

Step-by-step explanation:

The formula for interest compounded continuously is

[tex]A = Pe^{rt}[/tex]

Data:

P = $1400

r = 2 % = 0.02

Calculations:

(a) Calculate A

A = 2 × 1400 = $2800

(b) Calculate t

 [tex]2800 = 1400e^{0.02t}[/tex]

        [tex]2 = e^{0.02t}[/tex]     Divided each side by 1400

 ln2 =  0.02t               Took the ln of each side

     t = ln2/0.02          Divided each side by 0.02

     t = 34.66 yr

It will take 34.66 yr for the investment to double at 2 % interest compounded continuously.

Check:

2800 = 1400e^{0.02×34.66}

2800 = 1400e^{0.6931}

2800 = 1400 × 2

Answer:

One rose bush = $3

One bunch of ornamental grass = $4

Step-by-step explanation:

We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:

[tex]14r+7g=70\\5r+14g=71[/tex]

We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:

[tex](*-2)14r+7g=70\\5r+14g=71\\-------\\-28r-14g=-140\\5r+14g=71\\--------\\-23r=-69\\r=\frac{-69}{-23}=3[/tex]

Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:

[tex]14r+7g=70\\14(3)+7g=70\\42+7g=70\\7g=70-42\\7g=28\\g=\frac{28}{7}=4[/tex]

Thus, 1 bunch of ornamental grass is $4.

Lisa has a total of 8 dresses in her closet. There are 2 red dresses, 3 green dresses, and the remaining 3 are blue dresses.

The subject of the question is probability in Mathematics. In the problem, Lisa has a total of 2 red dresses and 3 green dresses. The quantity of blue dresses is represented by 'x'. It is stated that the probability of choosing a red dress is 25%. Each dress in her closet is an outcome for this probability calculation.

So, in total, she has 2(red dresses) + 3(green dresses) + x(blue dresses) = 100% of the dresses or total outcomes. Since the probability of picking a red dress is 25%, then 2 (red dresses) are 25% of the total outcomes.

To work out the total number of outcomes (total dresses), we calculate 100% ÷ 25% = 4, and then multiply this by the number of red dresses (which is 2), giving us 4*2 = 8 dresses in total.

As we know there are 2 red dresses and 3 green dresses, that leaves 8 (total dresses) - 2 (red) -3 (green) = 3 blue dresses. Thus, Lisa has three blue dresses in her closet.

Lisa has 6 blue dresses.

To find the number of blue dresses Lisa has, we need to set up an equation using the given information.

Lisa has 2 red dresses, 3 green dresses, and x blue dresses. The total number of dresses is 2 + 3 + x = 5 + x.

The probability of choosing a red dress is 25%, which can be written as 0.25.

This means that the number of red dresses divided by the total number of dresses equals 0.25. So, we have 2 / (5 + x) = 0.25.

Solving this equation for x, we find that Lisa has 6 blue dresses.
