Rosa says she can break this array(6 rows,8 in each row) into 3 different sets of two smaller arrays. is rosa correct. explain

Arrays are dataset that are represented in rows and columns

Rosa's claim is correct.

From the question, we have:

The number (n) of elements in the array is:

So, we have:

Express as sum of three numbers

Express each term as a product

The above expression means that, the array can be split to:

An array of 2 by 6An array of 4 by 4An array of 5 by 4

Hence, Rosa is correct.

Rosa is correct

Step-by-step explanation:

Rosa has array (6 rows and 8 columns). She can break this array into two smaller arrays in such ways:

1st array (5 rows and 8 columns) and 2nd array (1 row and 8 columns);1st array (4 rows and 8 columns) and 2nd array (2 rows and 8 columns);1st array (3 rows and 8 columns) and 2nd array (3 rows and 8 columns);1st array (6 rows and 1 column) and 2nd array (6 rows and 7 columns);1st array (6 rows and 2 columns) and 2nd array (6 rows and 6 columns);1st array (6 rows and 3 columns) and 2nd array (6 rows and 5 columns);1st array (6 rows and 4 columns) and 2nd array (6 rows and 4 columns).

So, there are even more than 3 different ways.

A. -10 is the value of x

The answer to that is 6
