A farmer wants to build a rectangular pen for her goats by enclosing a rectangle of land bordered with a side of the barn as one side of the region and with a fence on the other 3 sides. The farmer has a total of 125 feet of fencing.
Write a function of one variable for the area of the pen.

ome people is not even worth it to even try it in the air.

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
