a. Analyze the equations in Problem 2. What is the pattern? Use the pattern to find the next 4 facts. Show your work. 11 × 9 = 12 × 9 = 13 × 9 = 14 × 9 = Kent notices another pattern in Problem 2. His work is shown below. He sees the following: The tens digit in the product is 1 less than the number of groups. The ones digit in the product is 10 minus the number of groups. Use Kent’s strategy to solve 6 × 9 and 7 × 9. Show an example of when Kent’s pattern doesn’t work.
