Answer 2

Let's simplify the expression using the order of operations, also known as PEMDAS:

1. First, we need to calculate 42*7, which is 294.
2. Next, we can subtract 294 from 320, which gives us 26.
3. Now we can multiply 47 by 26, which gives us 1222.
4. Finally, we can add 65 to 1222, which gives us the final answer of 1287.

Therefore, 47*(320-42*7)+65 = 1287.
