which of the following numbers can be arranged into arrays with two rows? 9,16,2,15,20,33

Any of them.

if you meant equal rows....

only the ones divisible by two can be

16, 2, & 20

To determine which of the following numbers can be arranged into arrays with two rows, we need to find the numbers that have exactly two factors.

Step 1: Find the factors of each number.

Factors of 9: 1, 3, 9
Factors of 16: 1, 2, 4, 8, 16
Factors of 2: 1, 2
Factors of 15: 1, 3, 5, 15
Factors of 20: 1, 2, 4, 5, 10, 20
Factors of 33: 1, 3, 11, 33

Step 2: Count the number of factors.

Number of factors of 9: 3
Number of factors of 16: 5
Number of factors of 2: 2
Number of factors of 15: 4
Number of factors of 20: 6
Number of factors of 33: 4

Step 3: Select the numbers with exactly two factors.

The numbers with exactly two factors are 2 and 15. These numbers can be arranged into arrays with two rows.

Therefore, the numbers 9, 16, 20, and 33 cannot be arranged into arrays with two rows.
