daniel would like to construct a frame for his painting. he has 50 inches of framing material that will form the perimeter of the frame. write the fuction a(x) to represent the area of the frame which is x inches long. after you write you equation for a(x), change it to the standard form

Solution

length = x inch
total perimeter = 50 in
2*(length + width) = 50
length + width = 25
width = 25-x
width = (25-x)inch

Area = length * width
a(x) = x (25-x)
= 25x - x^2
