 Question 257344: Hi! Im having difficulty understanding why my answer is wrong in the following problem: In triangle ABC, centroid D is on the median "AM". "AD"= x+6 and "DM"= 2x-5. Find "AM" anything with the quotations means that it is a line. so i solved it by these steps: 1) 2x-5 = x+6.....x=11 2) 11+6=17, 22-5=17 ( i did this because i substituted x into the equations given for the length of "AD" and "DM" 3) "AM"= 34 Please help me!
