A picture is 6 inches longer than it is wide and has an area of 167
Scorpion4ik [409]

Answer:

A) L = W + 6

B) L * W = 167  OR L = 167 / W

Substituting B) into A)

167 / W = W + 6

Multiplying both sides by "W" we get

167 = W^2 + 6W

W^2 + 6W -167

Solving by the quadratic formula

Width = 10.266

Length = 16.266
