Which statement about sqrt x-5 minus sqrt x=5 true? -3 is a true solution -3 is a extraneous solution 9 is a true solution 9 is a extraneous solution

9 is an extraneous solution.

Step-by-step explanation:

Extraneous solution is a solution that when plugged into the equation do not hold true.

Here we are given an algebraic equation in terms of single variable x as:

Now, we will solve this equation to obtain the solution as:

on squaring both side of the equation we obtain:

Again on squaring both side of the equation we obtain:

Now when we plug x=9 back to the original equation i.e. equation (1) we get:

Hence, the equation does not hold true.

Hence, 9 is a extraneous solution

the answer is 16ft
