Question

Which expression is equivalent to 4(x + 3) - 2(-x - 5)?

Answer 1

4x + 12 + 2x + 10

Explanation:

4( x + 3 ) -2( -x -5 )

1. Multiply 4 and x = 4x

2. Multiply 4 and 3 = 12

3. Multiply -2 and -x = 2x

(turns positive as there are 2 negative signs)

4. Multiply -2 and -5 = 10

(turns positive as there are 2 negative signs)

Answer 2

the last one because when using the distributive property, you get

4x + 12 - 2x - 10
