If by w2 you mean "w squared", then it cannot be done. BECAUSE w2 + 49 = 0 w2 +49 - 49 = 0 - 49 w2 = -49 w2 means a number multiplied by itself. Any number multplied by itself will result in a POSITIVE number. positive x positive = positive negative x negative = negatve
there are 14 line sgments
IDKKKKKKKK
w2+18w+77 = (w+7)(w+11) when factored
L + W = P/2 = 34, so L = 34 - W;L x W = 280 or (34 - W) x W = 280 ie 34W - W2 = 280 which is W2 - 34W + 280 = 0This factorises as (W - 14)(W - 20) so the sides are 14 and 20 feet, the latter being the longer.
