What whole number best approximates the value of x?
100
102
103
104

I'm pretty sure your answer should be approximately 10.2 because if its asking what "x" is closest to, then 10.2 would be the number it is closest to on the number line. Hope this helps you ^-^
Answer
104
Explanation
The √x from the number line is about 10.2.
Or say less than 10.2. The number is also much greater than 10.1.
If you square 10.2 to get the value of x;
10.2² = 104.04
So, the approximate value of x is 104.
