Enter your answer in the box.

Answer 1

Answer:

-147

Step-by-step explanation:

We can solve this by plugging in p = 5 and q=−2 and then evaluating using PEMDAS which tells us the order we do the math in by operation

Remember,

PEMDAS means

Parenthesis

Exponents

Multiplication and Division ( perform going left to right )

Addition and Subtraction ( perform going left to right )

-3(p-q)²

==> plug in p = 5 and q = -2

-3(5-(-2))²

==> remove parenthesis on -2

-3(5 + 2)²

==> do the operations inside of the parenthesis

-3(7)²

==> do the exponents

-3(49)

==> multiply -3 and 49

=-147
