What multiplication fact can be found by using the arrays for 2x9 and 5x9?

To find the multiplication fact, we need to understand the concept of arrays. An array is a rectangular arrangement of objects or numbers. In the context of multiplication, an array represents the product of two numbers.

Given the arrays 2x9 and 5x9, we can visualize them as follows:

2x9:
[ ][ ][ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ][ ][ ]

5x9:
[ ][ ][ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ][ ][ ]
[ ][ ][ ][ ][ ][ ][ ][ ][ ]

To determine the multiplication fact, count the total number of objects or numbers in both arrays combined.

In the 2x9 array, we have 2 rows with 9 objects each, which gives us a total of 18 objects.

In the 5x9 array, we have 5 rows with 9 objects each, which gives us a total of 45 objects.

Therefore, when we combine the two arrays, we have a total of 18 + 45 = 63 objects.

Hence, the multiplication fact that can be found by using the arrays for 2x9 and 5x9 is 63.
