4n is multiplied by 4n.
The expression (3n + 4n - 14) simplifies to (7n - 14) by combining the like terms (3n) and (4n). This represents a linear expression in terms of (n).

To simplify the expression (10n - 4n), you combine the like terms. Subtract (4n) from (10n) to get (6n). Therefore, the simplified expression is (6n).
20n2+6n-2 (4n + 2)(5n -1) This problem can be solved by FOILing. First, multiply the first terms to get 20n2 Next, multiply the outside terms to get -4n. Multiplication of the inside terms results in 10n. Combining -4n and 10n (they are like terms) is 6n. Then, multiply the last terms, to get -2. Combining these answers into one equation gives the answer of 20n2+6n-2.

8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
The LCM of 4n and 6n is 12n.

The expression "4n 12 3n - 3" seems to be missing some operators. Assuming you meant "4n + 12 + 3n - 3," you can combine like terms. This simplifies to (4n + 3n) + (12 - 3), resulting in 7n + 9. If the intended expression is different, please clarify.
