Answer:
Associative property
Step-by-step explanation:
Given: addition of matrices
To find: property shown in the matrix addition
Solution:
A matrix is a rectangular array in which elements are arranged in rows and columns.
Let A, B be the matrices and [tex]O[/tex] (zero matrix) denotes identity for addition
Inverse Property states that [tex]A+B=B+A=O[/tex] such that A and B are inverse of each other. [tex](B=-A)[/tex]
Identity property states that [tex]A+O=A=O+A[/tex]
Commutative property states that [tex]A+B=B+A[/tex]
Associative property states that [tex](A+B)+C=A+(B+C)[/tex]
The matrix addition given in the question shows Associative property.
