Answer:
D)
Step-by-step 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)
