What is the product?
Anit [1.1K]

The final answer will be a 3x3 matrix. So you'll have 3 rows and 3 columns.

Along row one, the values are:     10,   15,    20

Along row two, the values are:      45,  -5,   -35

Along row three, the values are:   55,  25,   -15

all of which make up the final answer. Each value in bold is the result of multiplying the outer 5 by each value inside the original matrix given. In a sense, it's like using the distributive property, though we wont be adding any of the values (everything stays separated).
