When using distributive property you take the number outside the parentheses, in your case the number 6 and you multiply it to every number inside the parentheses. So here you have (4+5)6, the first thing you wanna do is multiply 6 by 4 and then multiply 6 by 5. After you do that, you get 24+30=54.
During Distributive property, the number on the outside of the parenthesis basically gets multiplied by the numbers inside the parenthesis. In this case, you would multiply 6 by 5 and 4. When you get the products, then follow the sign that comes next. In this case, you would add the products to get a total sum. I attached a photo for further reference. Hope this helps!
