Let A be an nn matrix and b a column vector of size n. Let A denote the augmented matrix (A | b). Suppose that the system Ax = b has more than one solution. For each of the parts below, write your answer in a sentence. Do not answer only "yes" or "no". For example in part (a) your answer should be in one of the following forms: we can conclude that det(A) = 0. we can conclude that det(A) = 0. this conclusion depends on the vector b. (a) Can we conclude that det(A) = 0? or can we conclude that the det(A) = 0? or does this conclusion depend on the vector b? (b) Can we conclude that the system has infinitely solutions? or can we conclude that the system has finitely many solutions? or we can not make a conclusion based o
