Question

Am I correct?..

Answer 1

Is that the answer or do I square root it?

Answer 2

You need to isolate the numbers inside the radical. You can do this by adding 1 to the other side of the equation.
\[\sqrt{x + 5} = 3\]
Then you would square both sides. Squaring cancels out the radical on the left side.
\[x+5 = 3^{2}\]

Answer 3

Okay so x+5=9
subtract 5 from each side..
so x= 4 correct?

Answer 4

Right :)

Answer 5

How do I do this one?
