Step-by-step explanation:
![x+3\neq 0\\x\neq -3\\\frac{x^2}{x+3} =\frac{9}{x+3} \\x^2=9\\x=3](https://tex.z-dn.net/?f=x%2B3%5Cneq%200%5C%5Cx%5Cneq%20-3%5C%5C%5Cfrac%7Bx%5E2%7D%7Bx%2B3%7D%20%3D%5Cfrac%7B9%7D%7Bx%2B3%7D%20%5C%5Cx%5E2%3D9%5C%5Cx%3D3)
Answer:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Step-by-step explanation:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Answer:8.125 ft
Step-by-step explanation:
Given
Plastic pipes of 5 ft are cut into 8 rods
The length of each rod will be
![\Rightarrow \dfrac{5}{8}\ ft](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B5%7D%7B8%7D%5C%20ft)
The total length for 13 rods are
![\Rightarrow L=13\times \dfrac{5}{8}=\dfrac{65}{8}\ ft\\\Rightarrow L=8.125\ ft](https://tex.z-dn.net/?f=%5CRightarrow%20L%3D13%5Ctimes%20%5Cdfrac%7B5%7D%7B8%7D%3D%5Cdfrac%7B65%7D%7B8%7D%5C%20ft%5C%5C%5CRightarrow%20L%3D8.125%5C%20ft)
