For the first one, it dropped negative 30 degrees in a span of 6 hours. So, we divide - 30 by 6 and we get -5. It dropped negative 5 degrees per hour. For the second one, we factor 12. Negative times negative equals positive so both of the factors are negative. When we factor 12, we get 2, 2, and 3. -3 times -4 equals 12 and it adds up to -7. I hope this helps!
