Null matrix upper triangular matrix and lower triangular matrix

A matrix A=[a_(ij)] is an upper triangular matrix, if

If A is an upper triangular matrix of order nxxna n dB is a lower triangular matrix of order nxxna n dB is a lower triangular matrix of order nxxn , then prove that (A^(prime)+B)xx(A+B ') will be a diagonal matrix of order nxxn [assume all elements of A and dB to e non-negative and a element of (A^(prime)+B)xx(A+B^(prime))a sC_(i j) ].

Let R be a square matrix of order greater than 1 such that R is lower triangular.Further suppose that none of the diagonal elements of the square matrix R vanishes. Then (A) R must be non singular (B) R^-1 does not exist (C) R^-1 is an upper triangular matrix (D) R^-1 is a lower triangular matrix
