Length=2+3w Area= Length × Width 56= (2+3w)(w) 56=2w+3w^2 56-56=3w^2+2w-56 0=3w^2+2w-56 CONTINUATION IN THE PICTURE The width is 4 The length is 14; 2+3w 2+3(4) 2+12 14 I stated in the picture that a length cannot be negative. That doesn't mean -14/3 wouldn't work. You may use it if you want. HOPE THIS HELPS!!!
