Answer 2

D)

Explanation:

We have the expression A² and we need to evaluate this expression for A = -4.

To do this, we need to substitute the value given for A (in this case is -4) in the original expression A².

So this would give us:

A² = (-4)²

A² = (-4) (-4) *by the law of the signs we know that when two numbers with like signs are multiplied, the result is positive*

Therefore we would have

(-4) (-4) = 16.

Thus, A² for A = -4 equals 16 and the correct answer is D)
