It makes it easier to multiply. For example 2*52. It's easier to do 2*50 and then 2*2 and add it together. Product is 104
Answer: one sixth or 1/6
1/2 + 1/3 + ? = 1
5/6 + ? = 1
1 - 5/6 = 1/6
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)
