the length of a rectangle is 4 times the width.
let y be the width and x be the length.
Write a function for the perimeter of the rectangle as a function of x.
The perimeter:
p = 2x + 2y
"the length of a rectangle is 4 times the width. "
x = 4y but can we can also write this as: y = .25x and replace y with .25x
p(x) = 2x + 2(.25x)
p(x) = 2x + .5x
p(x) = 2.5x
