Answer and Step-by-step explanation:
The answer to this expression would be 6(3m + 7n).
18m + 42n is the distributive version of the same expression.
To un-distribute, you would find the greatest common factor of both numbers, and pull it out of the expression.
18 and 42 have a greatest common factor of 6.
18 divided by 6 is 3.
42 divided by 6 is 7.
<u>That leaves us with 6(3m + 7n).</u>
