Seems Joshua beat me, so the best I can do is show the work. I kinda have to since I was called out in the most recent post. :)x^2 + (x+1)^2 = 1105x^2 + x^2 + 2x + 1 = 11052x^2 + 2x = 1104x^2 + x = 552x^2 + x + .25 = 552.25(x+.5)^2 = 552.25x + .5 = 23.5x = 23I did miss the bicycle riddle and the "what's special about this number" riddle. Straight math like this is a bit easier for me. :)
I think I have the smartest readers on the planet.

ReplyDeletex^2 + (x+1)^2 = 1105
x^2 + x^2 + 2x + 1 = 1105
2x^2 + 2x = 1104
x^2 + x = 552
x^2 + x + .25 = 552.25
(x+.5)^2 = 552.25
x + .5 = 23.5
x = 23
