Answer:-3a + 3 + 8b
Step-by-step explanation: 2 and 5 have the same variable so they can be called the "like" terms
The formula of a volume of a rectangle prism:
![V=lwh](https://tex.z-dn.net/?f=V%3Dlwh)
l - length
w - width
h - height
We have
![l=n^2+2;\ w = 10,\ h=n+5](https://tex.z-dn.net/?f=l%3Dn%5E2%2B2%3B%5C%20w%20%3D%2010%2C%5C%20h%3Dn%2B5)
Substitute:
![V=(n^2+2)(10)(n+5)=(10n^2+20)(n+5)\\\\=(10n^2)(n)+(10n^2)(5)+(20)(n)+(20)(5)\\\\=10n^3+50n^2+20n+100](https://tex.z-dn.net/?f=V%3D%28n%5E2%2B2%29%2810%29%28n%2B5%29%3D%2810n%5E2%2B20%29%28n%2B5%29%5C%5C%5C%5C%3D%2810n%5E2%29%28n%29%2B%2810n%5E2%29%285%29%2B%2820%29%28n%29%2B%2820%29%285%29%5C%5C%5C%5C%3D10n%5E3%2B50n%5E2%2B20n%2B100)
<h3>Answer: V = (10n³ + 50n² + 20n + 100) in³</h3>

Answer:
- 7 ; 7 pounds loss in weight.
