#3: -3h-5
The others look ok
1. (9m+6)+(-5m-6)
my answer: 4m
2. (3r^2+7r+1)+(4r^2-8r-2)
my answer: 7r^2-r-1
3. (6h-1)-(9h+4)
my answer: -3h-3
4. (m^2-m-4)+(m-5)
my answer: m^2-9
5. (4x+4)+(3x+2+1)
my answer: 7x+7
Now this was book work for me so it doesn't have multiple choice, so are my answers correct?
