Answer: -45
Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here, we have 7 + -12 which is -5.
When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.
Now, we have (-5) (9).
Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.
Therefore, (7 + 12) × 9 = -45.
