Question

Edwards is making a rectangle picture frame he wants the perimeter of the frame to be no more than 96 inches he also wants the length of the frame to be a greater than or equal to the square of 4 inches less than it’s worth

Answer 1

length, l width, w

perimeter, p = 2(l+w)...eqn 1

l = w -16...eqn 2

subst for l in eqn 2 into eqn 1...

p = 2((w-16) + w)

p = 4w -32

using p = 96, 96 = 4w -32, w = 32 inches

l = w- 16 = 16inches
