yes

See, Mrs. Jones wanted to make twenty headbands. It takes 7 ribbons to make one headband, so you would need to multiply that by twenty, and that equals 140.

Answer 13

can you help me with more

Answer 14

Yeah

Answer 15

Look at the expression below.

2 + 4xy + 8x + 10 – 3x + 5y

a. Rewrite the expression so that LIKE TERMS are grouped together.

b. Simplify the expression

Answer 16

Like terms are the terms that have the same variable and exponent. 2 and +10 are like terms, +8x and -3x are like terms.

Answer 17

ok

Answer 18

Simplify by combining LIKE TERMS.

five m plus two n plus n

five m plus three n

seven m n

five m plus two n

ten m n

Answer 19

12+4xy+5x+5y

Answer 20

So, when you combine the terms it would look like this: 2 + 10 + 4xy + 8x - 3x + 5y

Answer 21

ok thxs

If so, I already said the simplified answer.

Answer 37

5x + y(4x + 5) + 12

Answer 38

or 12 + 5x + y(4x + 5)
