True or false? a. The determinant of a matrix is a scalar. false true b. The determinant of a matrix is always positive since it is the absolute value of a number. false true c. The determinant of a 5 x 6 matrix can be written as a linear combination of the determinants of thirty 1 x 1 matrices. false true = d. If A and B are 1 x 1 matrices, then det A + det B false true det(A + B). e. If A and B are 2 × 2 matrices, then det A + det B = det(A + B). false true
