Answer 1

Answer: I haven't taken my quiz again, but these answer choices I chose are definitely incorrect.

Hopefully this helps eliminated one of the incorrect answers.

Answer 2

B is correct

Explanation:

When we add or subtract matrices, we combine respective parts of the matrices. For example, since 3 is respective to -1, we do 3-(-1)=4. And also since 2 is respective to 0, 2-0=2.

Hope this made sense.
