Answer:

x = 126

Step-by-step explanation:

Square both sides of the equation. (sqrt2x+4)^2 = 16^2

2x+4 = 256

Then you should solve for x. (First Subtract 4 from both sides; Then simplify; Next divide both sides by 2; Finally, simplify once more)

This should give you your answer. (x = 126)

Hope this helps! ^-^

Answer:

x = 72

Step-by-step explanation:

sqrt {2x} +4 = 16

sqrt {2x} = 12

2x = 12 ^ 2

x = 144/2

x = 72

If you wanted to write:

sqrt {2x + 4} = 16

2x + 4 = 16 ^ 2

2x + 4 = 256

2x = 252

x = 252/2

x = 126
