b= -2
Step-by-step explanation:
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)
58.50 - 45 = 13.50
13.50 / 45 x 100 = 30%
answer: mark up 30%
Answer: 123
They have to add up to 3 4 5 6 or 7 so it has to be that
