Question

Help Please!! 30 points !! What is the solution to the equation √(2x+8 )-6=4. Show your work.

Answer 1

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

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