Compute each matrix sum or product if it is defined. If an expression is undefined, explain why. Let A = D-[-24] D= -1 - 2A, B-2A, AC, CD - 2A = (Simplify your answer.) O B. The expression - 2A is undefined because matrices cannot be multiplied by numbers. O c. The expression -2A is undefined because matrices cannot have negative coefficients. OD. The expression - 2A is undefined because A is not a square matrix. 3 0 -3 5 -5 4 O A. B= Compute the matrix product - 2A.
