Can you please take a picture of the question?
This equation involves no x variable, so I assume you want to solve this for D.
First of all, you can divide both sides by 0.785 to get
Since the right hand side is positive, the equation make sense (otherwise we would be asking a square, i.e. a positive number, to equal a negative number). So, we can extract the square root from both sides:
Yes 4 is a value of the solution.
If we plug in 4 to s we get:
4+6 <= 12
10 <= 12
and 10 is in fact less than 12
