Answer:
r = -4
Step-by-step explanation:
2r + 7 = - 1
2r = - 1 - 7
2r = - 8
Answer: r=-4
Step-by-step explanation: -3(2r + 7)=3 (−3)(2r)+(−3)(7)=3 −6r+−21=3 −6r−21+21=3+21 -6r/-6=24/-6 r=-4
The volume would be 31 cubic feet.
To find this, use the formula for the area of a right pyramid.
A = 1/3bh
A = 1/3(8)(12)
A = 1/3(96)
A = 32
