Lines & Points

[symone]

A, B, C are points on a line with AB = 8.4 in., BC = 2.9 in.
What is the length of AC if (a) B is between A and C, (b) C is between A and B?

Re: whoa

Assuming you mean "lengths" rather than "points", then, for one of the parts, yes; for the other part, no.

this is really confusing to me. Please help!!!

Please review the "help" provided in the previous reply (and here). Then draw the suggested pictures, and look at them.

If you still have questions, please reply with specifics. Thank you.
