OA. -3a2 + 4ab + 36

OB. -3a2 + 252 + 8ab + 36

O C. -5a2 + 4ab

36

OD -5a2 + 252 + 8ab + 36

The equivalent expression is:

Step-by-step explanation:

An equivalent expression to the one given can be found removing first from the parenthesis, and then combining the like terms. So

Removing from the parenthesis

Combining the like terms:

The equivalent expression is:

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.
