Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation
![4\left(n\right)-3=-2\left(n\right)+9](https://tex.z-dn.net/?f=4%5Cleft%28n%5Cright%29-3%3D-2%5Cleft%28n%5Cright%29%2B9)
remove the parentheses
![4n-3=-2n+9](https://tex.z-dn.net/?f=4n-3%3D-2n%2B9)
Add 3 to both sides
![4n-3+3=-2n+9+3](https://tex.z-dn.net/?f=4n-3%2B3%3D-2n%2B9%2B3)
Simplify
![4n=-2n+12](https://tex.z-dn.net/?f=4n%3D-2n%2B12)
Add 2n to both sides
![4n+2n=-2n+12+2n](https://tex.z-dn.net/?f=4n%2B2n%3D-2n%2B12%2B2n)
Simplify
![6n=12](https://tex.z-dn.net/?f=6n%3D12)
Divide both sides by 6
![\frac{6n}{6}=\frac{12}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6n%7D%7B6%7D%3D%5Cfrac%7B12%7D%7B6%7D)
Simplify
![n=2](https://tex.z-dn.net/?f=n%3D2)
Therefore, the value of n = 2.
Hence,
Yes!

Step-by-step explanation:
Are 6 and 15 the legs of the triangle?
Cone's volume is
![V = \frac{1}{3}Sh](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cfrac%7B1%7D%7B3%7DSh)
where S - surface area, h - height
Surface area =
![\pi r^2](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E2)
r = 18/2=9
h= 14
π = 3.14
![V= \frac{1}{3} \pi r^2h= \frac{1}{3} *3.14*9^2*14= \frac{1}{3} *3.14*81*14=27*14*3.14](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Cpi%20r%5E2h%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A3.14%2A9%5E2%2A14%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2A3.14%2A81%2A14%3D27%2A14%2A3.14)
