## Homework Statement

Find algebraically:

[tex]\lim_{x\rightarrow 7} {\frac{3x}{\sqrt{x+2}}} [/tex]

## Homework Equations

None

## The Attempt at a Solution

[tex] {\frac{3x}{\sqrt{x+2}}} * \frac{\sqrt{x+2}}{\sqrt{x+2}}[/tex]

[tex] \frac{3x\sqrt{x+2}}{x+2}[/tex]

In most of these problems, I get the limit of a square root + another number and I'm able to factor. This problem just threw me off. How should I proceed?
