Answer:
Yes. It works.
Explanation:
3 x (4 + 5) = First you have to add 4 + 5 since it's in parentheses, and whatever is in parentheses, you have to do it first. so 4+ 5 = 9. Then you multiply 9 by 3 which gives you 27.
(3 x 4) + (3 x 5) is equivalent to 3 x (4 + 5).
First you do whatever is in parentheses, since they're both in parentheses, I don't think it matters which you do first, but I would do the first problem. 3 x 4 is equal to 12, then 3 x 5 is equal to 15, so you add your answers. 12 + 15 = 27.
So, you can write 3 x (4 + 5) as (3 x 4) + (3 x 5) = 27. They both equal to 27. Hope this clarifies your question.
Also the property is called the distrubitive property.
