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

If you would like to calculate 1/2 * a + (-3 * a) - 3 * b - 0.7 * a, you can do this using the following steps:
1/2 * a + (-3 * a) - 3 * b - 0.7 * a = 0.5 * a - 3 * a - 0.7 * a - 3 * b = - 3.2 * a - 3 * b
The correct result would be - 3.2 * a - 3 * b.
