Answer:
The answer is C. 4.5. Hope that helps.
Step-by-step explanation:
The volume of a pyramid is V = 1/3 x base length^2 x height
Let X = base length.
We are told the height is 1/2 the length, so height would be 1/2x
Now we have:
972 = 1/3 * x^2 * 1/2x
Simplifying we get:
972 = 1/6x^3
Multiply both sides by 6:
5832 = x^3
Take the cube root of both sides:
x = 18
The length of the base is 18 inches.
The height is 1/2 that, so the height would be 18/2 = 9 inches.
a^4+2a+8 because if you combine like terms that is what you get
Answer:
This would mean 3x=5
so to isolate the x, we divide 5 by 3
and get x=5/3
