Answer:
3. solid , liquid
4. respiratory
I only know these two answers and I'm not sure if it's right
Your answer is 4
You have to use the distribute property and distribute the - to the -7 and the 3
The -7 will become and the 3 will become -3
Then you add those together and when you add a negative to a positive you basically subtract
So 7+-3 is 4
A is your answer
15 is the answer because 8-5 is 3 and 3 and 4 is 12 so 12 plus 3 is 15
