I know its pretty simple but my brain feels like scrambled eggs so can someone help me out on this?

Answer 2

start with \(x^2+(x+7)^2=17^2\) and solve carefully

Answer 3

what do you do with the (x=7)^2? Do you FOIL it out?

Answer 4

you square it, yes.

Answer 5

that is what i meant by "carefully" do not write \((x+7)^2=x^2+49\) or your teacher will think you are a moron
write \((x+7)^2=x^2+14x+49\)

Answer 6

\[2x^2+14x=240\]

Answer 7

What next? (Im sorry, but i can barely see straight right now so im in no thinking condition)

Answer 8

240
