What is the length of line AD?

OpenStudy (kymber):

Just count the segments

OpenStudy (lime):

-7 + 8 or 8 - -7?

OpenStudy (anonymous):

2nd

OpenStudy (kymber):

Think about it, -7 + 8 wouldn't make any sense, since that equals one and it's obviously not one :P

OpenStudy (lime):

That makes more sense than I originally thought. I tend to "over-think" most things. Thanks.

OpenStudy (kymber):

:D
