lol i just rechecked my work and I'm an idiot. i had 24/9 but i divded both by 3 but the i just decided not to include the /3 part. lol @ me thanks for the help tho

k thx

c=8 i think

sqrt x squared is just X. but i get confused with the middle terms. I am going to try it later on when i have the time to, i'll get back to you

how can i cross multiply that without getting utterly lost?

okay I'm definitely lost now. i have the stated question i sqaure both sides, i get \frac{25}{7 + 2((\sqrt{7})(\sqrt{3\sqrt{x}})) + 3\sqrt{x}} = 7 + 2((\sqrt{7})(\sqrt{-3\sqrt{x}})) + 3\sqrt{x}

okay so square both sides to get rid of the first square root sign then square again to get rid of the one on the "x" ?

i don't understand how you got that could you explain it please?

i cross multiplied, but I'm a little iffy on my FOIL technique when square roots are throw into the mix

Homework Statement \frac{5}{\sqrt{7+3\sqrt{x}}} = \sqrt{7 -3\sqrt{x}} Homework Equations none The Attempt at a Solution does this equal 5 = 7 - 3\sqrt{x}

okay so should my answer be x = +/- 16, +/- 9?

Homework Statement 25|x| = x^2 + 144 Homework Equations none The Attempt at a Solution okay well, I'm not quite sure what to do, do i try to isolate the |x|? and then break it up into a positive and negative? |x| = (x^2 + 144)/25 ? but from here i become lost...

so times buy a form of one... 1 over cosacosb?

Homework Statement Prove that: tan (a - b) = tana - tanb 1 + tanatanb] Homework Equations cos (a- b) = cosacosb + sinasinb sin (a - b) = sinacosb - cosasinb The Attempt at a Solution I have plugged in the two...
