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

Answer: the answer is 100
Step-by-step explanation:
Because 25 times 4 equals 100 use a Calculator
This means that if the model is 1 in lengh then th ereal car is 20 times of that or 20 in legnth
so to find the answer, just multiply model by 20
8.7 =model
real=8.7 times 20=174
real car is 174 inches
12 inches=1 foot
conversion factor
1 ft/12in=1=convesion
so
174 times 1/12=14 and 6/12
the answer is 14 feet and 6 inches or 14.5 feet
