Answer 3

no i got 7 and it was wrong the answer is 49/16

Answer 4

\[\sqrt x+2+\sqrt x=4\]

Answer 5

I see, the 2 is under the square root as well.
So its sqrt(X+2) + sqrtx =4

square both sides so you get: x+2+2sqrt(x^2+2x)+x=16

simplify: sqrt(x^2+2x)=7-x

square both sides: x^2+2x=49-14x+x^2

get all x's on one side: 16x=49

solve for x: x=49/16
