If x denotes the length of one side of the rectangle perpendicular to the building, determine the function in the variable x giving the area (in square feet) of the fenced-in region.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

she will most likely have 33  

step-by-step explanation:

the correct answer is the second option
