How do you solve this ?

Answer:

- 21 - 24 n.

Step-by-step explanation:

Given  : 3(-7-8n)

To find : Solve by  Distributive property .

Solution : We have given 3(-7-8n).

Distribute 3 over -7 and - 8n .

3 * - 7+ 3 * -8n .

- 21 + ( -24 n).

- 21 - 24 n.

Therefore, - 21 - 24 n.

Answer:

C. B = 38°

Step-by-step explanation:

A vertical angle is created when two lines intersect, and are a pair of two non adjacent angles that are opposite from the origin, so both angles are going to measure the same.

Since both vertical angles are the same, both measure 38º.

Vertical angles are shown in the image:In this case the angle A would be the omega, and the B is the alfa.

Answer:

infinitely many solutions

Answer:

Option A is the answer.

Step-by-step explanation:

The area of the triangle is given as :

[tex]A=\frac{1}{2}\times base\times height[/tex]

Base will be given by :

[tex]\sqrt{(x1-0)^{2}+(y1-0)^{2}}[/tex]

= [tex]\sqrt{x1^{2}+y1^{2}}[/tex]

Similarly the height will be given by:

[tex]\sqrt{(x2-0)^{2}+(y2-0)^{2}}[/tex]

= [tex]\sqrt{x2^{2}+y2^{2}}[/tex]

Now, putting these dimensions in the formula we get:

[tex]\frac{1}{2}\times \sqrt{(x1^{2}+y1^{2})(x2^{2}+y2^{2})}[/tex]

Therefore, option A is the answer.

So I will be assuming that EG = 8 is the length of the line segment EG. If that's the case, therefore the coordinates of G would simple be:

G =11 ± 8

G = 11 – 8, 11 + 8

G = 3, 19 

So G can have a coordinate of 3 or 19.

The coefficient is the multiplication constant with a variable thus in the expression 3x/13 + 4 the number 3/13 will be the coefficient.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

It is known that the coefficient is the constant which is in multiplication with a variable.

In general, variables are represented by x,y, and z.

The given expression is 3x/13 + 4.

Here,x is a variable therefore the term 3/13 will be a coefficient.

Hence "The coefficient is the multiplication constant with a variable thus in the expression 3x/13 + 4 the number 3/13 will be the coefficient".

To find Milo's age given Westley's age and the fact that Westley is 3 years younger than Milo, we can set up a subtraction equation and solve for Milo's age.

To find out how old Milo is, we can use the given information that Westley is 9 years old and 3 years younger than Milo. We can set up a subtraction equation by subtracting 3 from Westley's age.

Let's represent Milo's age as 'x'. The equation would be:

Westley's age - 3 = Milo's age

Substituting Westley's age of 9 into the equation:

9 - 3 = x

Simplifying the equation:

x = 6

Therefore, Milo is 6 years old.

The pattern A, B, A, C repeats every four terms. Dividing the term number (20) by the length of the repeating sequence (4) yields 5 with no remainder, indicating the twentieth term will be the same as the fourth term - which is 'C'.

The given pattern A, B, A, C, A, B, A, C is a repeating sequence that occurs in sets of four (A, B, A, C). To ascertain the twentieth term in this pattern, divide the term number by the length of the repeating sequence. That would be 20 divided by 4, which equals 5 with no remainder. That suggests the twentieth term will be the same as the fourth term in the sequence, which is C.

Now solve across.

14 x 2 = 28

  1 x 7 = 7

Now we have this fraction.

[tex] \frac{28}{7} [/tex]

Now this also means

28 ÷ 7 = 4

So the answer to your fractions is 4.

Answer:

True.

Step-by-step explanation:

If the two trinomials are given as

x³ + 2x² + 4 = 0

and

2x³ + x² - 3 = 0

Then by adding these trinomials we get

(x³ + 2x² + 4) + (2x³ + x² - 3) = 0

3x³ + 3x² + 1 = 0

Which proves that sum of two trinomials is ALWAYS a trinomial.

So the answer is True.

Answer:

The required equation is 2b+3=15.

Number of bats = 6

Number of baseballs = 9

Step-by-step explanation:

Let b be the number of bats.

It is given that there are 3 more baseballs than bats in a dugout.

Number of baseballs = b + 3

Number of bats and baseballs in the dugout in all is

[tex]Total=b+(b+3)[/tex]

[tex]Total=(b+b)+3[/tex]

[tex]Total=2b+3[/tex]

There are 15 bats and baseballs in the dugout in all.

[tex]2b+3=15[/tex]

The required equation is 2b+3=15.

Subtract 3 from both sides.

[tex]2b=15-3[/tex]

[tex]2b=12[/tex]

Divide both sides by 2.

[tex]b=6[/tex]

The value of b is 6. So, the number of bats is 6 and number of baseballs is 6+3=9.

Answer:

Rays AB and AC both have a point in common. That is the A point or normally called the vertex. From the point both go in different directions making a distance between both. This distance has a degree in which it separated that forms the angle. This also forms a line because both rays, in theory, are lines. They just tend to continue to infinity in just one direction.
