Question

Ab = |-2 - (-6)|=
ac = |0 - (-6)|=

Answer 1

On this number line:

A is at -6, B is at -2, C is at 0, and D is at 4.

AB = |-2 - (-6)| = |-2 + 6| = |4| = 4

AC = |0 - (-6)| = |0 + 6| = |6| = 6

AD = |4 - (-6)| = |4 + 6| = |10| = 10

BC = |0 - (-2)| = |0 + 2| = |2| = 2

BD = |4 - (-2)| = |4 + 2| = |6| = 6

Answer 2

AB = 4

AC = 6

AD = 10
