If AC equals 6 and BD equals 4, then AB equals 5.

yes because ab plus bc is ac
the midpoint of AB.

ac + cb = ab = 9 2x - 1 + 3x = 9 5x -1 = 9 So 5x = 10 Thereby x =2. Also ac = 3 and cb = 6
There are some missing terms. First of all, I assume that A, B, and C are collinear and that B is between A and C.If this is true then AC-AB=BC by the whole is the sum of its parts theorem.24-20=4Otherwise, all that can be said about BC is that it's length is between AC-AB = 4 and AC+AB = 44 units.
ac is 7 if b is 3 and a is 2 a nd c is 5
It could be a vector sum.
