-36

Step-by-step explanation:

To evaluate the expression, you want to plug in r to solve.

-40(-31-16(-2))²+(-2)²              [parenthesis]

-40(1)²+(-2)²                             [exponent]

-40+4                                       [add]

-36

Now we know the expression is equal to -36 when r=-2.
