- MATH - insufficient information -
**MathMate**, Monday, September 5, 2011 at 7:18amPlease write in "proper case", it is easier to read.

"Points A,B, and C are collinear. If AB=7 cm and ??=13 cm, what are AC's answers? "

Need to confirm what is 13 cm.

In this case, I assume BC to be 13 cm.

There are two possibilities:

A----7------B-----13------C

or

C--6---A---7-------B

Bet you can take it from here.
