I hate homework!
To break a 4x7 array into a 2x7 array and another array, we can divide the original array into two parts by splitting it vertically.
The 2x7 array will be formed by taking the first two rows of the original array. Let's call this array A.
To find the second array, we will take the remaining two rows of the original array. Let's call this array B.
Now, let's find the dimensions of array A and array B:
- Array A: 2x7 (2 rows and 7 columns)
- Array B: 2x7 (2 rows and 7 columns)
The number sentence that models the relationship of the 4x7 array to the other two arrays can be written as:
4 x 7 = 2 x 7 + 2 x 7
This means that the total number of elements in the original array (4x7) is equal to the sum of the number of elements in array A (2x7) and the number of elements in array B (2x7).
