Remmeber yo can do antyhing to an equation as long as you do it to both sides
9x>270
divide both sides by 9
x>30
B/4<4
times both sides by 4
B=16
Y/5≤8
times both sides by 5
Y≤40
5c≥125
divide both sides by 5
c≥25
Answer: first option
Step-by-step explanation:
The volume of a regular pyramid can be calculated with the following fromula:

Where B is the area of the base of the pyramid and h iis the height of the pyramid.
The base is a square, therefore, its area B is:

You know that the height is 3, therefore, you can substitute these values into the formula.
THerefore, the volume of the pyramid is:


If you are trying to figure out how much it will cost:
8 x 4 = 32
Cost of gas = $32
Either one at any given time could be equal to zero. So
x + 2 = 0
x = - 2
x - 18 = 0
x = 18
I've enclosed a graph of this so you can see that the answers I've given are the ones expected.
