Question

Select all the expressions that are equivalent to (screenshot below)

Answer 1

Explanation:

Use the Distributive Property:

`-2(5x-1)+7(5x-1)-3(5x+1)`

`-10x+2+35x-7+15x-3`

P is correct.

Simplify:

`40x-8`

T is correct using FOIL or distribution.

Use the FOIL method to simplify:

Use 5x-1 then multiply with -2, 7, and -3.

Note: With -3, -5x + 1 is in the parenthesis, we need to change -3 to 3.

Changing -3 to 3 will equal the distribution of -3(-5x+1).

Our expression:
`(5x-1)(-2+7+3)`

S is correct.
