Question

My last question please help I keep getting it wrong!!​

Answer 1

1. Divide by 4
sqrt 2x+8 = 6

2. Square both sides to remove square root
2x+8 = 36

3. Subtract 8
2x = 28

4. Divide by 2 to make x by itself
x = 14

Answer 2

Answer:

4

$4 \sqrt{2(2) + 8} = 4 \sqrt{4 + 8 } = 4 \sqrt{12} = 4(6) = 24$
