a. Luke looks at the line plot and says that all odd numbers of unit squares produce only 1 rectangle. Do you agree? Why or why not?
b. How many X’s would you plot for 4 unit squares? Explain how you know.

Answer:
a. Luke looks at the line plot and says that all odd numbers of unit squares produce only 1 rectangle. No, I disagree with the Luke’s statement because only prime numbers have factors as itself and number one. Here, numbers 7 and 11 are prime numbers not odd numbers, so they have only formed one rectangle.

b. Number of rectangles formed by 4 unit square are only 2 because number 4 has factors as 1 and itself and number 2.

Explanation:
