Given that ab = ba and bc = cb We can arrive at abbc = cbba by adding equal quantities to both sides of the equation By the cancellation law you're allowed to drop the bb from both sides of the equation to end up with ac = ca
I am going to go with never , really.

it is the crossproducts property...right that down now...
the midpoint of AB.
C is the midpoint of Ab . then AC = BC. So AC= CB.
The real answer is Bc . Hate these @
(a - t)/(b - t) = c => a - t = c(b - t) = cb - ct = bc - tc => tc - t = bc - a => t(c - 1) = bc - a => t = (bc - a)/(c - 1)
It is the property of commutativity.
ac + cb = ab = 9 2x - 1 + 3x = 9 5x -1 = 9 So 5x = 10 Thereby x =2. Also ac = 3 and cb = 6

If CB is the hypotenuse, then AB measures, √ (62 - 52) = √ 11 = 3.3166 (4dp) If AB is the hypotenuse then it measures, √ (62 + 52) = √ 61 = 7.8102 (4dp)
bc equals st multiplied by the scale factor.
