What is the approximate value of x?

Answer:
The answer is 17.
Step-by-step explanation:
Let the number plotted be x.
The point plotted on number line is slightly more than 4.
And this number is the square root of x.
We know that [tex]\sqrt{16}[/tex] is 4.
And the given point is close to 4 or square root of 16.
So, the best possible and closest answer is 17.
The square root of 17 is 4.123.
Therefore, the answer is 17.
