Answer:
11.25 minutes
Step-by-step explanation:
The capacity of the swimming pool is 105 gallons of water.
There are currently 15 gallons of water
∴I need to fill (105-15) = 90 gallons of water
Now,
8 gallons of water are filled within 1 minute
∴1 gallon of water will be filled within = 1/8 minute
∴90 gallons of water will be filled within = 90/8 minutes
=11.25 minutes
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4
