Intro to matrix multiplication

Let A be a square nxn matrix. Which of the following statements are equivalent to "A is an invertible matrix"?A has a pivot in every column.A and In are row equivalent.AX = b is always consistent.The columns of A form a linearly dependent set.Ax = 0 has the trivial solution.Given the matrix A below, which row or column would you expand across to compute the determinant by cofactor expansion? We are allowed to expand across any row or column; the point is for you to choose what would be most effi
