Resposta:

Explicação passo a passo:

C

c11=2.1-3.1=2-3=-1

c12=2.1-3.2=2-6=-4

c13=2.1-3.3=2-9=-7

c21=2.2-3.1=4-3=1

c22=2.2-3.2=4-6=-2

c23=2.2-3.3=4-9=-5

c31=2.3-3.1=6-3=3

c32=2.3-3.2=6-6=0

c33=2.3-3.3=6-9=-3

|-1 -4 -7 |

|1 -2 -5|

|3 0 -3|

D

d11=3.1-2.1=3-2=1

d12=3.1-2.2=3-4=-1

d13=3.1-2.3=3-6=-3

d21=3.2-2.1=6-2=4

d22=3.2-2.2=6-4=2

d23=3.2-2.3=6-6=0

d31=3.3-2.1=9-2=7

d32=3.3-2.2=9-4=5

d33=3.3-2.3=9-6=3
