Question

If: AB= 2x + 6, AC = 51, and BC=6x +5, Find BC.

Answer 1

Assuming A, B, and C are collinear and B is between A and C then BC = 35

Explanation:

Assuming A, B, and C are collinear and B is beetween A and C

AB + BC = AC

2x + 6 + 6x + 5 = 51

8x + 11 = 51

8x = 40

x = 5

BC = 6x+5 = 6×5 + 5 = 35
