Question

The equation below shows the perimeter f(x) of several rectangular side tables having width x inches:

f(x) = 24 + 2x

The perimeter of each table is less than 50 inches. Which of the following best describes the domain of f(x)?

Answer 1

All integers greater than 0 and less than 13

All integers greater than 0 and less than 50

All real numbers greater than 0 and less than 13

All real numbers greater than 0 and less than 50

Answer 2

f(x) <=50

f(x) = 24 + 2x
50 <= 24 + 2x

I've got the problem started, can you do the next steps to isolate x?

Answer 3

im not sure how to isolate x

Answer 4

we want to move the 24 to the other sides first, could you do that for me? or do you need help?
