Pump 1 can empty a pool in 5 hours while Pump 2 can empty the same pool in 9 hours. If the two pumps were to work
together, how long would it take them to empty the pool?

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
