yes

Answer 3

Type it in and I will try to help you.

Answer 4

(2x)(10x)

A 20x
B 12x
C 20x^2
D 5x

Answer 5

(2x)(10x)

What do we get when we multiply the coefficients (2 and 10)?

Answer 6

20

Answer 7

Correct. Now, we will multiply x times x. Do you know what that equals?

Answer 8

x

Answer 9

It is actually x^2 (x squared). When we multiply the variables, we add the exponents. Each x has an exponent of 1. We add the two exponents together to get 2. Do you get it?

Answer 10

so it is c

Answer 11

Yes. It is c.

Answer 14

-3m(m+8)

A -3m^2+24
B -3m^2-24m
C -24m^2
D -4m+5

Answer 15

i think its a or b

Answer 16

Ok. Let's start by multiplying -3m and m together. Just like the other one, we will multiply the coefficients together and the variables together. Do you know what we would get?

Answer 17

We can start by multiplying the coefficients together. (-3 and 1). We would then multiply m and m together just like we did with the last problem.

Answer 18

-3m^2

Answer 19

Correct! Next, we will multiply -3m and 8 together. The variable will just be m. What will the coefficient be? In other words, what does -3 times 8 equal?

Answer 20

-24m

Answer 21

so is it b
