Answer:

6x³+3x-6

Step-by-step explanation:

To add the polynomials, combine like terms:

4x³+2x³-2x+5x-9+3

4x³+2x³ = 6x³;

-2x+5x = 3x;

-9+3 = -6

This gives us

6x³+3x-6

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out
Evgen [1.6K]

1/the rate of leakage per hour

This will give you the time it takes for 1 gallon to leak out in hours.  

For example, if something is leaking at the rate of 12 gallons per hour, it will take 1/12 of an hour for 1 gallon to leak out. ( or 5 min)
