Answer:
x=2
Step-by-step explanation:
We know the only number that gets us back to 0 after subtracting 4 is 4, because 4-4=0. The square root of 4 is 2. Hope my explanation wasn't too confusing!
2²=4
4-4=0

Answer:
750 ft^3
Step-by-step explanation:
Given that the cones are similar, the first step would be to determine their linear scale factor; That is the ratio of their radii;
![\frac{RadiusB}{RadiusA}=\frac{30}{12}=2.5](https://tex.z-dn.net/?f=%5Cfrac%7BRadiusB%7D%7BRadiusA%7D%3D%5Cfrac%7B30%7D%7B12%7D%3D2.5)
The next step is to determine the volume scale factors. Since the linear scale factor is 2.5, the volume scale factor would be;
volume scale factor = (linear scale factor)^3
= 2.5^3 = 125/8
The volume of Cone B will thus be;
volume of Cone A * volume scale factor = 48 * 125/8 = 750 ft^3
