Simplify the expression. Plug in -2 for x
Your answer should be 15

The answer is actually “A,” 11, because if you distribute the 2 across the parentheses, you‘re left with “2x+10+3+2.”

This simplified equals 2x+15

then plug in your “x” value (which is -2)

2(-2)+15=?

then further simplify:

-4+15=11

ANSWER: 11
