Answer 2

Answer:

C. A square matrix A is invertible if and only if det(A) = 0

Step-by-step explanation:

A square matrix is invertible if and only if the determinant is not equal to zero. In other words, a 2 x 2 matrix is only invertible if the determinant of the matrix is not 0. If the determinant is 0, then the matrix is not invertible and has no inverse. #SPJ3
