9n+18(2n-6)+13

First, use distributive property to eliminate the parenthesis:
9n + 18(2n -6) + 13
9n + 36n - 108 + 13

Next, combine like terms:
9n + 36n - 108 + 13
45n - 108 + 13
45n + 121

Hope this helps!!

So first we would have to use the distributive property for 18(2n-6). When you distribute it, it comes to 9n+36n-108+13. Then we combine like terms which is 9n+36n and -108+13. 9n+36n = 45n. and -108+13 = -95. Since we can't simplify it any further the final answer is 45n-95. Hope this helps :)
