Answer:
The width is 20 inches, the length is 32 inches and the height is 15 inches.
Step-by-step explanation:
Let x inches be the width of the box. If the length of the box is 12 inches greater than its width, then the length of the box is x+12 inches. If the height of the box is 5 inches less than its width, then the height of the box is x-5 inches.
The volume of box is
Therefore,
Solve this equation:
The integer solutions of this equation can be among the divisors of -9600. The divisors of 9600 are:
We can check all these divisors and see that x=20 is a solution, then using synthetic division
Since the quadratic factor has discriminant we can state that the only solution is x=20 inches. The width is 20 inches, the length is 32 inches and the height is 15 inches.
So you would simplify scence you cant subtract simplify the variables then do your normal steps of pemdas
the answer is 5 if you need an explanation ask for it in the comments
Your answer just going to be 0.5x
