Let A be a 2 x 3 matrix and B be a 3 x 2. Which of the following gives a 3 x 3 matrix as a result? Select one alternative: BA

Let A and B be the following matrices: A 5 2 0 94] -4 4 B www 4 -2 - -4 3 Find the matrix product A B:

Consider the two matrices: Compute A + 3B. The result is equal to: Select one: O a. O b. 0 с. O d. 5/2-11/2) -15/2 (- (4, -13) -12 6 none of the others (-₁5--1¹) 6 O e. 3(B+ A/2) 2 4 A = (²₁6) B=(-²32) -6 0

Let A and B be the following matrices. Perform the following operations: AB = BA= [] A = [59 3-9], 8 ] B = -3 4

AB BA If A = False [4] and then B = [44] -2 -2 and True or False: AB = BA for any two square matrices A and B of the same size.

Consider the following matrices: and A = B 12 3 4 2 = 1 Find the products AB and BA or say why they are not defined.

Suppose B is a 9x9 nonzero matrix. Explain answer to the following questions cleary each

If 4A - 3B = 2C (where A, B and C are all matrices) then Matrix A can be defined as: %3D Select one: a. 0.5C + 3B b. (2C+3B)/4 C. 0.5C + 0.75B d. C + B

Use the following matrix. A =  -1 −2 0 3 2 1 5 2 1 What is the sum of matrix A and its negative?
