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:
x = 48
Step-by-step explanation:
14^2 + b^2 = 50^2
196 + b^2 = 2500
-196 -196
b^2 = 2304
√b^2 = √2304
b = 48
This depends on a lot of factors. A persons weight, height, etc. It also depends on how many calories they want to burn or if they are just looking to run for fun. A lot of different factors play into a persons time to jog.
So if you're driving 25 miles per hour, it would take you 7 hours to drive 175 miles.
175 miles ÷ 25 miles = 7 hours.
