The expression 8 + 2 * 8 represents the total number of dots in the array, which is 24.
Which expression is represented by the array?
The array can be represented by the following expression:
8 + 2 * 8
This expression represents the total number of dots in the array.
- The first term, 8, represents the number of dots in the top row.
- The second term, 2 * 8, represents the number of dots in the bottom two rows.
Since there are two rows in the bottom part of the array, we multiply 8 by 2 to get the total number of dots in that part.
So, the expression 8 + 2 * 8 represents the total number of dots in the array, which is 24.
