The equation C = AB requires that (a) Both C and B must have the same number of rows, but the number of columns can be different. (b) Both C and B must have the same number of columns, but the number of rows can be different. (c) Both C and B must have the same number both of rows and columns. (d) It is not possible for the number of columns of C to equal the number of rows of B . (e) It is not possible for the number of rows of C to equal the number of columns of B . 2. The equation C = A + B requires that (a) Both C and B must have the same number of rows, but the number of columns can be different. (b) Both C and B must have the same number of columns, but the number of rows can be different....
