It is impossible for three prime numbers less than 30 to add up to 1955. After all, 30+30+30 is only 90.

The two numbers that multiply to -30 and add up to 13 are 15 and -2. When you multiply 15 and -2, you get -30, and when you add them together, you get 13.
Let one number be x. so the other will be x+6. They add up to 30 so x+x+6=30 so 2x+6=30 => 2x = 30-6=24 => x=24/2=12 So the two numbers are 12, 12+6=18.
