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
