Suppose that A is an n x n matrix and that A is invertible. Select all of the following statements which are true: From the 6 choices, select all that apply The columns of A form a basis form R" The rows of A for a basis form R" The columns of A span R" The rows of A are linearly independent The columns of A are linearly independent n The rows of A span R“

Plz  correct solution  only other wise lots of dislikes.

Let x=(4,3, 1, 1) and y (8, 2, 7, 1). Determine which of the following statement(s) is/are true: (i) xy is a scalar (ii) xy" is a matrix (iii) yx is a matrix (iv) xyx is a vector O a. (ii), (i) and (iv) only O b. (i), (ii) and (iv) only Oc. All of the above O d. (i), (ii) and (iii) only.

33. Prove that the row vectors of an n x n invertible matrix A form a basis for Rn.
