Answer:
2(x +14) = 40 (use the distributive property)
2x + 28 = 40 (solve exactly like you did for Fran)
2x = 12
x = 6
Answer: A
Step-by-step explanation:
-12 is made positive so the equation is turned to 12-3 which is 9
The volume of a rectangular pyramid is
V = (1/3) A*h
where
A = the area of the rectangular base
h = the height
The two pyramids are congruent in volume.
The volume of one pyramid is
(1/3)*(2*7.5)*(6) = 11
The volume of the composite figure is 2*11 = 22
Answer: 22
