Answer 1

The solution for the equation
`√(x + 2) = 7` is x=47. Therefore, the correct option is (d) 47.

To solve the equation
`√(x + 2) = 7`, 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:

`√(47+2) = 7`

49 = 7

7=7

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