what multiplication facts can be found using the arrays 2*9 and 5*9?

Well, let me put on my mathematician clown nose and calculate the multiplication facts for you!

Using the array 2*9, we have:

2 * 9 = 18

And for the array 5*9, we have:

5 * 9 = 45

So, the multiplication facts you can find using these arrays are 18 and 45. Ta-da!

To find the multiplication facts using the arrays 2*9 and 5*9, we can use the concept of multiplication.

The array 2*9 represents two rows and nine columns. It can be visualized as:

| | | | | | | | | |
| | | | | | | | | |

The array 5*9 represents five rows and nine columns. It can be visualized as:

| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |

To find the multiplication facts, we need to count the total number of items in each array.

For the array 2*9, we count the number of items in one row, which is 9, and then multiply it by the number of rows, which is 2. So, 2*9 = 18. This gives us the multiplication fact 2*9 = 18.

For the array 5*9, we count the number of items in one row, which is 9, and then multiply it by the number of rows, which is 5. So, 5*9 = 45. This gives us the multiplication fact 5*9 = 45.

Therefore, the multiplication facts using the arrays 2*9 and 5*9 are 2*9 = 18 and 5*9 = 45, respectively.
