Answer 2

Jaleel is correct

Step-by-step explanation:

Given

`2(x - 2) + 2`

Jaleel

`2(x - 2) + 2 = 2x - 4 + 2 = 2x - 2`

Lisa

`2(x - 2) + 2 = 2x - 2 + 2 = 2x`

Required

Who is correct

Analyzing the solutions

For, Jaleel; we have:

`2(x - 2) + 2 = 2x - 4 +2` --- this is correct

`2(x - 2) + 2 = 2x - 2` --- this is correct

For Lisa, we have:

`2(x - 2) + 2 = 2x - 2+2` --- this is incorrect because:

`2(x - 2) + 2 \\e 2x - 2+2`

Hence, Jaleel is correct
