Vocaloid (vocaloid):

hint: let x = length of a leg let x + 12 = hypotenuse use the pythagorean theorem to find x

OpenStudy (atrineas):

yeah just what is pythagorean theorem?

Vocaloid (vocaloid):

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

Vocaloid (vocaloid):

so yours would be x^2 + x^2 = (x+12)^2 solve for x

OpenStudy (atrineas):

x^4=(x+12)^2 x^4-x^2-24x-144=0 x=-3 x=4 I think...

Vocaloid (vocaloid):

nope not quite

Vocaloid (vocaloid):

what is x^2 + x^2?

OpenStudy (atrineas):

Umm 2x^4?

Vocaloid (vocaloid):

nope not quite hint: x + x = 2x x^2 + x^2 = ?

Vocaloid (vocaloid):

[you don't add the exponents]

OpenStudy (atrineas):

oops 2x^2?

Vocaloid (vocaloid):

good try solving for x again

OpenStudy (atrineas):

x=-12 x=12

OpenStudy (atrineas):

?

Vocaloid (vocaloid):

@agent0smith sorry my battery is about to die

Vocaloid (vocaloid):

would you mind checking

OpenStudy (agent0smith):

x^2 + x^2 = (x+12)^2 Plug your x back into this, and see if it's true when x=12. (-12 makes no sense... it's a triangle)

OpenStudy (agent0smith):

I'm pretty sure 12^2 + 12^2 does not equal 24^2.
