Question

(x)^2+(x+7)^2=(13)^2
this is the set up for this word problem...... The length of one leg of a right triangle is seven inches more than the length of the other leg @Mchilds15

Answer 1

Do I need to solve it for you?

Answer 2

I don't know where to go from there i set it up but i don't know how to solve it

Answer 3

I see. Okay so, we're solving for x, right?

Answer 4

yes

Answer 5

its using the Pythagorean theorem

Answer 6

Sooooooo basically you have x^2 + x^2 + 49= 169

Answer 7

what do i do with the (x+7)^2

Answer 8

basically the problem is xsquared + x+7squared=13squared

Answer 9

Lol the x^2+49 is the (x+7)^2

Answer 10

ok

Answer 11

My equation is the simplified version.
Anywho, now that you have x^2 + x^2 + 49= 169, you need to simplify it
So, what are you going to do first?

Answer 12

do I combine the like terms which is the xsquared and xsquared??

Answer 13

Hm..... I'm second guessing myself... But yeah, do that, then subtract the 49 from 169.
(I haven't done this in years, so sorry if this ends up wrong. I'm trying to remember)

Answer 14

so when u ccombine those wont it be 2xsquared??

Answer 15

Yep

Answer 16
