Answer:
Step-by-step explanation:
The top and bottom segments have same length.
a)
- n + n + 19 = 33
- 2n + 19 = 33
- 2n = 33 - 19
- 2n = 14
- n = 14/2
- n = 7
b)
- x + x + x + 3 = 30
- 3x = 30 - 3
- 3x = 27
- x = 27/3
- x = 9
Answer:
Surface Area = 150.8 square inch
Step-by-step explanation:
![Surface \ Area = 2 \pi r h + 2 \pi r^2 \ \ \ \ \ \ \ \ \ \ \ \ \ [ \ r = 4 , \ h = 2 \ ] \\\\](https://tex.z-dn.net/?f=Surface%20%5C%20Area%20%3D%202%20%5Cpi%20r%20h%20%2B%202%20%5Cpi%20r%5E2%20%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%20%5C%20r%20%3D%204%20%2C%20%5C%20h%20%3D%202%20%5C%20%5D%20%5C%5C%5C%5C)

6 ,because if n=2 you divide 12 by 2 and get 6
If you would like to solve the equation 9/11 = x/22, you can calculate this using the following steps:
9/11 = x/22 /*22
x = 9/11 * 22
x = 18
The correct result would be 18.
