Answer:
undefined
Step-by-step explanation:
x²-7x=12
we make the equation equal to zero by subtracting 12 from both sides, we have..
x²-7x-12 = 12-12
x²-7x-12= 0
we find the factors of 12 such that when we multiply them we will get -12 and when we add them we will get -7, and those factors are but those values are not possible..
so answer = undefined

Answer:
V = pi*x^2*(18x - 45)
Step-by-step explanation:
If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.
Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:
V = pi*(3x)^2*(2x - 5), or V = pi*(9x^2)(2x -5), or:
V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)
