I believe it’s -6ax - 35b + 48c, sorry if it’s wrong
For this case we have that by definition, the volume of a rectangular prism is given by:

Where:
It is the area of the base of the prism
h: It is the height

Where:
w: is the width
l: is the length
According to the data of the statement we have:

Substituting the data we have:

We choose the positive value: 
So the height is
Answer:

Answer:
(
)
Step-by-step explanation:
The fastest way to do this is to convert both equations into slope-intercept form and graph it to find the solution point. If you wanted to do this algebraically, you might want to start out by getting rid of the fractions and using either substitution or elimination to find x and y.
