Help Please!! 30 points !!<br> What is the solution to the equation √(2x+8 )-6=4. Show your work.
anastassius [24]

\sqrt{(2x + 8)}  - 6 = 4
\sqrt{(2x + 8)}  = 4  + 6

\sqrt{(2x + 8)}  = 10
\sqrt{(2x + 8)} ^{2}  = 10 {}^{2}
2x + 8 = 100
2x = 100 - 8
2x = 92
x = 92 \div 2
x = 46
So; the answer is: 46
