another way :
in a standardized test you may want to use real numbers
make x equal a prime number like 3

92
then divide by 4
23
then divide by 3
which is 7 remainder of 2
which is
7x+2

Step-by-step explanation:
The amount of empty space inside the cubic box is equal to the volume of the box minus the volume of the softball.
If the side length of the cubic box is , and the volume of the softball is
, then the amount of empty space
inside is
,
where is the volume of the cubic box.
Since it matches the equation we got above, choice B stands correct.
