Question

What is the value of the expression when x = 3, y = 5, and z = -4?

Answer 1

answer: D. 327

explanation:
just plug in the numbers for their corresponding letter!

7(3²)(5) - (3)(-4)
= 7(9)(5) - (3)(-4)
= 315 - (-12) = 315 +12
= 327

Answer 2

7 x ^2 y - 3 z

= 7 * (3)^2 * 5 - 3 * - 4

= 7 * 9 * 5 + 12

= 315 + 12

= 327

it's answer is D 327
