Question

Which choice is equivalent to the following equation?
x = (-4)^2 +27

Answer 1

C is your correct answer, I took this quiz :)

Answer 2

C. x = y^2 - 8y + 43

Explanation:

x = (y - 4)^2 + 27

(y - 4)(y - 4) = y^2 - 4y - 4y + 16

x = (y^2 - 8y + 16) + 27

x = y^2 - 8y + 43

The answer would be C. x = y^2 - 8y + 43.
