Answer:

-24

Step-by-step explanation:

Given expression:

      3z (2y - 4)²

  z = -2 and y = 3

To solve this problem, simply substitute:

       3z (2y - 4)² = 3(-2){2(3) - 4}²

                           = -6(6-4)²

                           = -6 (2)²

                          = -6 x 4

                          = -24

(T) S = D/T (T)

TS = D

Therefore, the final answer is D = TS
