Answer:
c. -45
Step-by-step explanation:
First we square -3
[tex]-5(-3)^{2}[/tex]
[tex]-5(-3*-3)[/tex] (a negative times a negative is positive)
[tex]-5(9)[/tex]
Then we multiply -5 by 9
[tex]-5(9)[/tex] = -45
We solve the problem in this order because exponents come before multiplication (PEMDAS).
So our final answer is -45
