Answer: The horizontal factor is 3
The vertical factor is x + 2y
The product should be 3(x + 2y) = 3x +6y
Step-by-step explanation: The values of the rectangles and squares are unknown (at least in this question-- unless the previous questions explain what values to use)
There are 3 columns
There is one row of large rectangles. I'm calling that x (you could use "r" )
There are two rows of squares. I'm calling those y, 2y for 2 rows. (could be "s")
Multiply the factors to get the product. 3 times the row of rectangles plus the two rows of squares.
I hope this helps. It has been a while since I have seen this kind of question.
