waht multiplication fact can be found by using the arrays for 2x9 and 5x9
2×9=18 5×9=45 take 18+45=63 so the answer is 7×9=63 get it got it good.
7x9=63

To find the multiplication fact that can be found by using the arrays for 2x9 and 5x9, you need to understand how arrays work.
An array is a rectangular arrangement of objects or numbers in rows and columns. In this case, we have two arrays: one for 2x9 and another for 5x9.
Let's start with the array for 2x9. It looks like this:
2 rows
9 columns
| * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * |
Each asterisk (*) represents one element.
Next, let's move to the array for 5x9. It looks like this:
5 rows
9 columns
| * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * |
| * | * | * | * | * | * | * | * | * |
To determine the multiplication fact, we need to count how many elements (asterisks) there are in total.
For the 2x9 array, we have 2 rows with 9 columns, which gives us a total of 2 x 9 = 18.
Similarly, for the 5x9 array, we have 5 rows with 9 columns, resulting in a total of 5 x 9 = 45.
Therefore, the multiplication fact that can be found by using the arrays for 2x9 and 5x9 is 18 multiplied by 45.
