Properties of Adjoint Matrices
For a 3 × 3 matrix M, let trace (M) denote the sum of all the diagonal elements of M. Let A be a 3 × 3 matrix such that |A| = 
and trace (A) = 3. If B = adj(adj(2A)), then the value of |B| + trace (B) equals:
and trace (A) = 3. If B = adj(adj(2A)), then the value of |B| + trace (B) equals:SELECT ONE OPTION
