Answer:
They're both proportional because everything's moving at a constant rate. Think of it this way: If a car travels for 50 miles per hour and the speed never changes, it's proportional. If that car at hour 1 traveled at 50mph and then at hour 2 traveled at 60mph, it would be nonproportional since the speed is increasing and changing.

Answer:
2 by 2
Step-by-step explanation:
The first matrix is 2 x 3; that is, it has 2 rows and 3 columns.
The second matrix is 3 x 2.
Following rules of matrix multiplication,
a 2 by 3 matrix multiplying a 3 by 2 matrix results in a product with the dimensions 2 by 2.
It's the division property of equality.
