the area of a rectangle is 9x^29x4 cm^2.
find its length and width then solve the perimeter
Am I missing something here? The roots are 1/3 and 4/3 but I can't seem to figure out how they would come out as the length & width
PLEASE HELP

Best ResponseYou've already chosen the best response.0but if x = 1/3 and 4/3 3(4/3) + 1 = 5 3(4/3)  4 = 0 ???
