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! ^-^
x = 72
sqrt {2x} +4 = 16
sqrt {2x} = 12
2x = 12 ^ 2
x = 144/2
If you wanted to write:
sqrt {2x + 4} = 16
2x + 4 = 16 ^ 2
2x + 4 = 256
2x = 252
x = 252/2

your answer is b bud... your welcome....
just took the test
D
Counting from 28 to 44, that is more than 27 miles
28, 31, 32, 33, 35, 39, 42, 43, 44
That is 9 ran more than 27 miles
i believe the 3rd one is it but yet im not for sure
