Since there are no actual values, I guess we just have to isolate the b.
2A=bh (multiply both sides by 2)
2A/h=b (divide by h)
hope this helps
Step-by-step explanation:
The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.
the expression for the volume of a cylinder is

the volume of a cone is a part of the volume of a cylinder

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3
The sub dives 37 feet....thats -37...it rises 16 ft....-37 + 16 = -21...then dives 18 ft.....-21 - 18 = - 39 ft
so the net change is -39 ft
4x^2 is the greatest commonly factor for these exponents.
Hope this helps you! :)
