Hey You!
255 / 4 = 63.75
Each side would be 63.75 square ft.
The only multiples of 4 between 1 and 10 are 4 and 8.
So 2/10 will have a multiple of 4, so the answer is 20%
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
x-------> the pressure in PSI
y------> the volume of the gas in cubic inches
In this problem we have the point 
so

Find the constant k

substitute the values of x and y


the equation is

therefore
<u>the answer is</u>

Answer: -5(7+2(-7))+15((7)+2(-7)) = -70
im not sure
