Answer 1

1. B and C

2. -10x-15

Explanation:

QUESTION 1

Lets substitute x for 1.

4-1=3 (Original)

A: 1-4=-3 (NOT Equivalent)

B: 4+-1=3 (Equal)

C: -1+4=3 (Equal)

D: -4+1=-3 (NOT Equivalent)

E: 4+1= 5 (NOT Equivalent)
Question 1 would be B and C.

QUESTION 2

The distributive property of multiplication over addition is applied when you multiply a value by a sum.

Lets get rid of the parenthesis by multiplying it.

5(-2x-3) = -10x-15

5 × -2x -10x

5 × -3 = -15
