Solve the equation<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%206%7D%20%20%2B%202%20%3D%206" id="TexFormula1" title
tensa zangetsu [6.8K]

Explanation:

First you had to square from both sides of equation form.

(\sqrt{x-6+2})^2=6^2

Then you expanded form.

(\sqrt{x-6+2})^2=x-4

x-4=36

6^2=6*6=36

Solve by equation form.

x-4=36

Add by four from both sides of equation form.

x-4+4=36+4

Simplify.

x=40

Verified solutions.

x=40 \boxed{TRUE}

Final answer: \boxed{x=40}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
