Multiplying -15 by 60 yields -900, so the amount of water in the pool changes by -900 gallons in one hour.
Your answer is 12.41x - 11.8
69% is the same as .69, which is the same as 69/100
Answer:
The answer is <u><em>7</em></u>!
Step-by-step explanation:
(x-4) (x) = 21, x^2 - 4x = 21, x^2 - 4x - 21 = 0, (x - 7) (x + 3) = 0, x = 7 and -3; x can't be negative so the answer is 7!
x = 7 and x - 4 (other side) = 3
