PLZ HELP ASAP One pump fills a tank 4 times as fast as another pump. If the pumps work together, they fill the tank in 20 minut
es. How long does it take for the faster pump to fill the tank?
1 answer:
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.

Answer:
(x-7) (x^2-5)
Step-by-step explanation:
x^3 -7x^2 -5x+35
Make 2 groups
x^3 -7x^2 -5x+35
Factor x^2 from the first group and -5 from the second group
x^2 (x-7) -5(x-7)
Now factor (x-7) out
(x-7) (x^2-5)
