Answer:
f(-1) = 0
f(2) = 16
Step-by-step explanation:
f(-1) = 4(-1) + 4 = 0
f(2) = 4(2) + 8 = 16
The volume for a pyramid is

where B is the base area and h is the height. We have both the area and the height, so we fill in our formula accordingly:

. That gives us a volume of 710 meters cubed.
7:
3/8 = 6/x
3x = 48
x = 16
8:
4/5 = (x+7)/40
160 = 5x + 35
5x = 125
x = 25
9:
3/8 = 12/(x-3)
3x - 9 = 96
3x = 105
x = 35
10:
4/1 = (3x+6)/x
4x = 3x + 6
x = 6
Answer:
-120
Step-by-step explanation:
A=-3
B= 4
5(-3)*2(4)
5(-3)= -15
2(4) = 8
-15*8 = -120
