ab = 8-cDivide both sides by ba = (8-c)/b
BS
A = 1, B = 9
Yes this true at one point in time
I think its BA.
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
no; commutative
ab = 8-cDivide both sides by ba = (8-c)/b

If these are vectors, then ba = - ab
A*B=B*A is an example of the commutative property of multiplication.
According to the symmetric property (and common sense) line segmetn AB is congruet to line segment BA since they are the same segment, just with a different name
A = 1, B = 9
The GCF is ab
Yes this true at one point in time
[(aa + bb) + (ab+ba)(aa+bb)*(ab+ba)]*[a + (ab+ba)(aa+bb)*b]
Yes.
