Question

Given the augmented matrix A = [1 1 -1 5 2 3 4 4 -4 -6 -2 -2] perform each row operation in the order specified and enter the final result [the resulting matrix] First r_2 = - 2r_1 + r_2. second: r_3 = 4r_1 + r_3, Third: r_3 = 2r_2 + r_3. If A. D. and C are 4 times 4.4 times 2. and 2 times 7 matrices respectively, determine which of the following products are defined. For those defined, enter the size of the resulting matrix (e.g. "3 times 4". with spaces between numbers and "x"). For those undefined, enter "undefined".
