Given:

A number line.

To find:

The correct values for points A, B, C and D.

Solution:

From the given number line is it clear that there are three marks between any two consecutive integers which divide the number line between those integers in 4 equal parts.

It means, one mark = .

In the number line, point A is at -2. So,

D is 1 mark below 0.

C is mark below -1.

B is 3 units below -1.

So,

Therefore, the correct option is A.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
