If M is a square matrix and t a real number then dettM t d

If M is a square matrix and t a real number, then det(tM) = t . det(M). Sometimes Always Never Let a be a real number. Then the matrix Sometimes Always Never The vectors (1/32,201,-3), (1/14,1/101,0),(0,15/51,101/17),and(21/2,0,-10 form a basis of R^3 sometimes Always Never Assume that A and B are n x n matrices. If A is not invertible and B is invertible, then AB is invertible. Sometimes Always Never If A and B are n Times n matrices. If A is not invertible and B is invertible, then AB is invertible Sometimes. Always Never The union of two subspaces of a vector space V is always a subspace of V. Sometimes Always Never
