The answer to number 15 is 4.47, or 4.5 because the line segment A & B starts from point 2, and ends at 6. The distance between 2 & 6 is 4. Instead, you started from point 0. So instead of putting 6x6, it should be 4x4, but nice try! :)
Great job Karen! Your scribe was very understandable, neat, organized and colorful (: and I agree with Marilen!
ReplyDeleteGREAT JOB KAREN! I liked the way you included a video, links, and pictures. Also, your scribe was understandable. Next time, only use colors for important words or numbers because your scribe would look like a bag of skittles :) Anyways, keep up the good work!
