3. If A is an n x n matrix with rank n, which one of the following statements is false? For any system Ax = b, the rank of the augmented matrix is less than n. The system Ax = b has a unique solution for any b. The system Ax = 0 has only the trivial solution. A is invertible The row-reduced echelon form of A is an identity matrix.

(b) The number of rows in $A$ must equal the number of columns in $B$. (c) $A$ and $B$ must have the same number of rows and the same number of columns. (d) $A$ and $B$ must both be square matrices.
