Answer:
h = 2y^6 +7
Step-by-step explanation:
Put the given values into the formula and solve for the unknown.
V = lwh
(20y^10 +70y^4) = (2y^3)·(5y)·h
Divide by the coefficient of h.
(20y^10 +70y^4)/(10y^4) = h = 2y^6 +7
_____
The rules of exponents apply. Here, you need the ones that say ...
- (a^b)·(a^c) = a^(b+c)
- (a^b)/(a^c) = a^(b-c)
