Answer 2

Answer:

A) [8 5]  B) [5 0]=k

   [-5 3]      [0 5]

Step-by-step explanation:

A)

[ 3 1] x [ 3 1] = [A B]

[-1 2]    [-1 2]   [C D]

A=(3x3)+(1x-1)=8

B=(3x1)+(1x2)= 5

C=(-1x3)+(2x-1)=-5

D=(-1x1)+(2x2)=3

B)

(A^2+7I)A^-1=k

[15 5]  x A^-1=k

[-5 10]

A^-1=1/7 x [2 -1]

                [1  3]  

[15 5]  x [2 -1] x 1/7 = k

[-5 10]    [1  3]

[35 0] x1/7 = k

[0 35]

[5 0] = k

[0 5]

Hope this helps.
