Points a, b, and c are collinear and b lies between a and c. if ac = 48, ab = 2x + 2, and bc = 3x + 6, what is bc?

Step-by-step explanation:

Look at the picture.

The equation:

       combine like terms

        subtract 8 from both sides

          divide both sides by 5

- put x = 8:

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
