What multiplication fact can be found by using the arrays 2 times 9 and 5 times 9
2*9 + 5*9 = (2+5)*9 = 7*9
did you actually try using some arrays?
To find the multiplication facts using arrays, you need to multiply the number of rows by the number of columns in each array.
For the first array, 2 times 9, we have 2 rows and 9 columns. So, the multiplication fact is 2 x 9 = 18.
For the second array, 5 times 9, we have 5 rows and 9 columns. So, the multiplication fact is 5 x 9 = 45.
Therefore, the multiplication facts that can be found using the arrays 2 times 9 and 5 times 9 are 18 and 45, respectively.
