Answer: 60 gallons
Step-by-step explanation:
5 minute = 30 gallons
10 minutes will use double as m uch water because it's double as much time
Therefore, it will use 60 gallons of water
The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is

. The third solution can be easily found using the rational root theorem, and it's equal to -1.
