Question

Ab + c^2 when a = 7, b = -3, and c = -4​

Answer 1

-21 + 16 = -5

Explanation:

7(-3) + (-4)
`^(2)`

Multiply the 7(-3), and the answer will be negative because we are multiplying a pos to a neg.

-21 + (-4)
`^(2)`

Do the exponent, this will be a positive because the exponent is by two so we multiply (-4) by (-4) so the signs match.

-21 + 16

Now solve.

-21 + 16 = -5
