#### Explanation:

#color(blue)"take the square root of both sides"#

#sqrt((p+7)^2)=+-sqrt216larrcolor(blue)"note plus or minus"#

#rArrp+7=+-6sqrt6#

#"subtract 7 from both sides"#

#pcancel(+7)cancel(-7)=-7+-6sqrt6#

#rArrp=-7+-6sqrt6larrcolor(red)"exact solutions"#

#### Explanation:

#### Explanation:

Alright, so we need to isolate the

To do that, we are going to start with taking the square root of both sides.

The square root and the square will cancel out so all we have to do is finish the equation!

Also, I would like to add that is not the exact number, IT IS AN APPROXIMATION. If you would like to have the exact number, see below. Since

Hope that helps!
