Your doing the Distributive Property. So in this equation your distributing the first 2 on the outside of the parenthesis, so this first section of your problem after distributing is 6n+8. Next distribute the -2 to the 2n and 5. DON'T FORGET THE NEGATIVE. So it would look like 6n+8-4n-10. Then combine like-terms. so 6n-4n = 2n. Then 8-10=-2. Your final answer should be
2n-2.
Hope this helped.
The original formula for the volume of a cone is

O.K. You give the approximate value of pi in the formula.

We have:

Substitute:

Answer: 7 cm.
Answer:
The answer is $16.45
Step-by-step explanation:
First, you have to multiply $0.95 x 9 = $8.55
Then, you have to subtract $25.00-$8.55 = $16.45
1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
