Question

Solve the equation. 4 times the square root of x minus 5 minus 8 = 12

Answer 1

\[4\sqrt{x-5}-8=12\]

Is this what you are asking?

Answer 2

yes

Answer 3

First step is get rid of that annoying radical sign :), but how?

Answer 4

by square rooting it i think

Answer 5

\[4\sqrt{x-5}-8=12\]
\[4\sqrt{x-5}=20\]
Divide both sides by 4
\[\sqrt{x-5}=5\]
Square both sides to get rid of the root
\[x-5=25\]
\[x=20\]

Makes sense? :)

Answer 6

x=30 sorry!

Answer 7

It does make sense :)
