Answer:
A
Step-by-step explanation:
T11 + V11 = 0.1 + 3.2 = 3.3; T12 + V12 = -10.5
This line all by itself limits you to a and b. That's because both answers A and B begin with t11 + v11= 3.3. You just add them as you see them. t12 + v12 = - 1.9 - 8.6 = -10.5
I'll finish off the addition, but you can see that A is right already.
t21 + v21 = 2.5 + 2.8 = 5.3; t22 + v22 = 8.2 - 1.4 = 6.8
t31 + v31 = -7.8 - 2.3 = -10.1; t32 + v32 = 1.4 + 5.1 = 6.5
That's how these matrices are added together.
