The solution for the equation
is x=47. Therefore, the correct option is (d) 47.
To solve the equation
, square both sides to eliminate the square root:
x + 2 = 7²
Simplifying, you get:
x+2=49
Now, isolate x by subtracting 2 from both sides:
x=47
So, the solution to the equation is x=47. Therefore, the correct option is (d) 47. You can verify the solution by substituting x=47 back into the original equation:

49 = 7
7=7
This confirms that x=47 is indeed the solution to the given equation.
