The area of a rectangular hot tub is (8x-2) square units. What are possible dimensions of the hot tub cover?

{1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.

{(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}.

Step-by-step explanation:

The area of the rectangular hot tub is (8x - 2) sq. units.

If the dimensions of the hot tub cover are all whole numbers, then the possible dimensions of the hot tub cover will be {1 unit by (8x - 2) units}, or {2 units by (4x - 1) units}.

On the other way, the dimensions may be {(8x - 2) units by 1 unit}, or {(4x - 1) units by 2 units}. (Answer)
