Answer 1

you actually mean sqrt-x as in \(\sqrt{-x}\)?

Answer 2

yes

Answer 3

oh wait you actually mean \(\sqrt{-x+6}\) not \(\sqrt{-x}+6\)

Answer 4

Square both sides :)

Answer 5

on the question its the first one

Answer 6

Just square both sides first :)
can we do this step by step?

Answer 7

To be honest I have NOOOOOOO idea what im doing !
Im failing algebra 2 EXTREMELY !!! but if you can go through
it thats fine too.. ILL TRY LOL :)

Answer 8

Could you square both sides? :)

Answer 9

would the square root be -x ?

Answer 10

well the sqrt isn't just to -x but to (-x+6) as a whole...

Answer 11

So we have: \[x=\sqrt{-x+6}\]
Squaring both sides and we get: \[x^2=-x+6\]

Answer 12

Answer 21

I'm not providing the direct answer, because the answer is useless.
What you need is not the answer, it's how to do more questions of this kind.

Answer 22

i went through each one & cant find it

Answer 23

x=2, so its D

Answer 24

and im 100% sure

Answer 25

\[x=\sqrt{-x+6}\]\[x^2=-x+6\]\[x^2+x-6=0\]\[(x-2)(x+3)=0\]\(x-2=0\) or \(x+3=0\)

\(x=2\) or \(x=-3\)

Therefore it's A and i'm 100% sure.

Answer 26
