Answer:
13.2 minutes or 13 minutes 12 seconds.
Step-by-step explanation:
1. Count how much water drains the first pump every minute. Let the volume of pool be D. Every minute first pump drains D/11 water.
2. Working together(6 minutes) First pump drains 6D/11 water, hence the second pump drains 5D/11 water.
3.Count how much water drains second pump per minute -> (5D/11)/6= 5D/66
4. It takes the second pump 66 minutes to drain pool 5 times, thus it takes 13.2(66/5) minutes to drain the pool, which is 13 minutes 12 seconds.

Answer:
The answer to your question is -3 and 2
Step-by-step explanation:
If an equation is factored, to find the roots, just equal each term to zero.
(x + 3)(x - 2) = 0
Equal each term to zero
x₁ + 3 = 0 x₂ - 2 = 0
Solve for x
x₁ = -3 x₂ = 2
The solutions to this quadratic equation are -3 and 2.
