Go to the number 4 on the number line. Draw a vertical line at this point: going up at 90 degrees to the number line. Measure 1 unit [ = the distance from 0 to 1] on this line and mark it as Y. Take a compass and put the point at 0. Take the pencil to the point Y and draw an arc to intersect the number lie at the point X. Then X is the required point, at sqrt(17).
On the number line it is -17
It is the square root of (-4-11)2+(17-17)2 which works out as 15.
The absolute value of a number is its distance from zero on the number line, regardless of its sign. In this case, the absolute value of 1.7 is 1.7, as it is a positive number and its distance from zero is 1.7 units.

The two possible candidates are 17 and 18. distance from 17.26 to 17 = 0.26 distance from 17.26 to 18 = 0.74 so 17 is the nearest whole number.
It is the square root of (-4-11)2+(17-17)2 which works out as 15.
