Points A, B, and C are collinear. Point B is between A and C. Find the length indicated
2) AC = x + 2, BC = 1, and AB = 2x - 4.
Find x, AB, and AC.

Answer:

            x = 5

            AB = 6

            AC = 7

Step-by-step explanation:

Points A, B, and C are collinear and point B is between A and C then

AB + BC = AC

2x - 4 + 1 = x + 2

2x - 3 = x + 2

   +3          +3

2x  =  x + 5

  -x     -x

  x  =  5

AB = 2x - 4 = 2×5 - 4 = 10 - 4 = 6

AC = AB +BC = 6 + 1 = 7
