Give an example. BUY. College Algebra (MindTap Course List) You can multiply a 2X3 matrix by which matrix below? * О 3х12 О 2х12 О 2х3 O 2x2. A: Can we add any two matrices together? If so, explain why; if not, explain why not and give an example of two matrices that cannot be Thus the formula to compute the i, j cofactor of a matrix is as follows: Where M ij is the i, j minor of the matrix, that is, the determinant that results from deleting the i-th row and the j-th column of the matrix. For example, let A be a 2×2 square matrix: We can compute the cofactor of element 1 by applying the formula (first row and oHoT.
