You can put this solution on YOUR website! B midpoint of AC: Given AB + BC = AC: Definition of a mid-point (the part that says a mid-point divides a line segment into two parts) AB = BC: Definition of a …

You can put this solution on YOUR website! As before, we factor a^2+2ab+b^2=25 and get (a + b)^2 = 25 Now take the root and get a + b = 5 and a + b = -5 Two solutions.

Question 129130: In a parallelogram ABCD,the bisector of angle A also bisects BC at X.Prove that AD = 2AB Answer by Edwin McCravy (20077) (Show Source):

If A and B are n×n matrices, then 〖 (A+B)〗^2=A^2+2AB+B^2. If A is an n×n invertible symmetric matrix, then (A^ (-1) )^k is symmetric, for any positive integer k.
