Best ResponseYou've already chosen the best response.0I missed it when I did (w+2)(w)... it equals w^2 + 2w.... NOT: w^2 + w my mistake

Best ResponseYou've already chosen the best response.0so this question here is a triangle: and we use the formula h^2 + b^2 = d^2 or whatever letter you wanna use. we know that the span is 4ft longer than its height

Best ResponseYou've already chosen the best response.0lets set it up: h^2 + (h+4)^2 = 20^2 h^2 + h^2 +8h +16 = 400

Best ResponseYou've already chosen the best response.02h^2 +8h +16 400 =0 2h^2 +8h 384 = 0 2(h^2 +4h 192) = 0...I hope im right so far :)

Best ResponseYou've already chosen the best response.02(0) = 0 so... h^2 +4h 192 = 0 h= 4/2 + sqrt(16  (4)(1)(192))/2

Best ResponseYou've already chosen the best response.0h = 14  2 = 12 h=12 and span =16.
