Step Number 1. is to Simplify
![\frac{4}{8} to \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B8%7D%20%20to%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Step Number 2. <span>Simplify so you get </span>
![\frac{x}{4} + \frac{5}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%2B%20%20%5Cfrac%7B5%7D%7B3%7D%20)
Done! :)
After 12 hours the pound would have 720 pounds of algae.
x^2 - 9 = (x + 3)(x -3)
3x - 9 = 3(x - 3)
and
6
Common denominator would be 6(x+3)(x - 3)
Answer: 6(x+3)(x - 3)
