Evaluate (-B) 2 for A = 5, B = - 4, and C = 2.

8

Step-by-step explanation:

Expression:

(-B) 2

Let's substitute the value of B into this expression:

B = - 4

(-B) 2

[ - (-4) ]2

Notice how there are two negative signs int this expression:

[ - (-4) ]2

Well, there is an invisible 1 behind the first negative sign.

[ - (-4) ]2

[-1 (-4) ]2

All we have to do now is multiply:

[-1 (-4) ]2

(4) 2

(4) 2

= 8

Therefore, the value of the expression is 8.
