Given are the following matrices: 9 65 D-8 4 3,E 10 0 1 +1. What is (it may be undefined): A 2B (A- B) B*B*C " T* A"D"C T* D+D (D+D)T 2. You can easily manipulate with rows and columns of a matrix by multiplying it with another matrix. You will see how by answering the following questions. a) Show that multiplying D from left with E, E*D, transforms matrix D such that its first row is multiplied by two, and its second and third rows are swapped. b) How does multiplying D from right with E, D*E, transform matrix D? c) Create matrix E, such that multiplying D from left with E, E*D, transforms D such that its second row is divided by 2 and its first and third rows are swapped. d) Create matrix E, such that multiplying D from left with E, E*D, transforms D such that its second row is the original second row minus the original first row of D
