I keep getting different answers!

I'll do it and come back to you with the answer and how to do it. You will need to use the Pythagorean Theorem I believe. 

Ok the Theorem is... $$a^2 + b^2 = c^2$$

3x + 2 * 3x + 2 = $$9x^2 + 4$$

4x - 6 * 4x - 6 = 

$$16x^2 + -36$$

$$9x^2 + 16x^2 = 25x^2$$

4 + -36 = -32

Final Answer = $$\sqrt{25x^2 - 32}$$

24.35?

or 5.65?

albert0898 · Answer

That's the simplest form there is. If you enter $$\sqrt{25x^2 - 32}$$ into a calculator...

you'll get a domain error.

I never did this before, you must understand that I'm in the 8th grade and haven't encountered such problems, but it seems as if you must you the Pythagorus.
