(a) If AB is a square matrix, then the multiplication BA can be performed. (b) det(ABA-!) = det(B) (c) For matrices A and B, if AB = 0 then either A = 0 or B = 0. (d) For any elementary matrix E, det (EA) = det(A). (e) If det(A) # 0 then the linear system Ar = b is consistent for any vector b. O la) O (b) (c) (d) O (e)
