Iven: δabc prove: the three medians of δabc intersect at a common point. when written in the correct order, the two-column proof below describes the statements and justifications for proving the three medians of a triangle all intersect in one point: statements justifications point f is a midpoint of point e is a midpoint of draw dr

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

the answer is simply just 6n add the two together as they have an n
