Answer: we need a picture
Step-by-step explanation:
If this was a cone, the volume would be 314.16.
- You would just put in the radius and height in the cone volume formula which is πr²h 1/3
If this is a cylinder then the volume would be 942.48
- Put in the radius and height in the cylinder volume formula which is πr²h
150 divided by 25 is 6, so I think it would be 6 hours to equal the total cost.
Consider expression
First, you can factor it:

Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus,
is always even.
