Question

I need helping... I'm doing the Pythagorean Theorem and here is what I have so far... 2b+2^2 +b^2 =13^2

Answer 1

are you solving for variable b?

Answer 2

Yes

Answer 3

want it rounded?

Answer 4

Yes that's fine

Answer 5

i'm not positive but i got b=8.6 (rounded)

Answer 6

Thank you though. Can I know the steps you took to solve it?

Answer 7

subtract 2 squared from both sides
so 13 squared is now 11 squared.
then divide by 2
so it is 121/2
then square root both sides
then b+b=2b so divide by 2 again
and b=8.6

Answer 8

sorry if it is confusing

It's okay. Thank you though
