Answer:
B:b=-2
Step-by-step explanation:
Choice D
You use the formula V=pi(radius^2)(h). Once you take the pi out and plug in the numbers, you should get V= 6^2(9). You get 324 with the pi added on after it.
Answer: c=7
8c = 56 Divide both sides by 8
c = 7
31.
8 + x/3 = -2
Substract both sides by 8:
x/2 = -10
Multiply:
x = -20
33.
6 * (x + 15) = -42
We can divide both sides by 6:
x + 15 = -7
Substract both sides by 15:
x = -22
