Compute each matrix sum or product if it is defined. If an expression is undefined, explain why. Let A = 6 -5 2 35 --[; : -]-[-²]-[-²]-~--[¯†1] B= D= 1 -3 -2 3 A + 3B, 4C-2E, DB, EB -4 23 OA. A+3B= 2 and E= -4 3 1 0-3 [:] 4-6 2 Compute the matrix sum A + 3B. Select the correct choice below and, if necessary, fill in the answer box within your choice. (Simplify your answer.) O B. The expression A+ 3B is undefined because A is not a square matrix. O C. The expression A+ 3B is undefined because A and 3B have different sizes. O D. The expression A+ 3B is undefined because B is not a square matrix.
