45 + 30 = 15(3 + 2) = 15(5) = 75
Answer:
the answer is Monomial I hope this helps
three squared minus two thirds

three square = 3 x 3 = 9

Least common factor of 1 and 3 is 3

Three squared minus two third is twenty five by three.
Answer:

For this case we know that
represent the radius,
the height and the rate given is:


And replacing we got:

And that represent 
Step-by-step explanation:
For a tank similar to a cylinder the volume is given by:

For this case we know that
represent the radius,
the height and the rate given is:

For this case we want to find the rate of change of the water level when h =6m so then we can derivate the formula for the volume and we got:

And solving for
we got:

We need to convert the rate given into m^3/min and we got:

And replacing we got:

And that represent
