Answer:
The volume of the small packing box is (2x^2 -5x + 10) inches^3
Explanation:
Here, we want to find an expression that represents the size of a small packing box.
We are told that the small packing box is a certain volume smaller than a large packing box and we are given the volume of the large packing box.
Thus, the number of inches with which it is smaller will be the volume of the large box minus the volume of the small box.
So to get the volume of the small
box, we will need to subtract the amount by which it is smaller from the volume of the large box.
Mathematically, that would be;
(5x^2 -2x + 10) - (3x^2 + 3x)
= 5x^2 -2x + 10 - 3x^2 - 3x
= 5x^2 -3x^2 -2x -3x + 10
= 2x^2 -5x + 10
