Below is the graph f(x). The function intersects its midline at (Pi,4) and has a minimum point at (Pi/4,-5.5).

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
