<em>The answer is 13 pounds (lbs.) and 4 ounces (oz.). There are 2 tents and each is 6 pounds. Add those together and that is 12 pounds. All that is left is to add the ounces. 10+10=20. Since there are only 16 ounces in a pound and we have 20 ounces, we add an extra pound and are left with 4 ounces. </em>
What are some of the questions you need help on?
That's not an equation. It's just an expression that stands for a number.

The largest "common factor" is 3mn .
So in factored form, the expression is 3mn (m + 4n) .
