1.What types of numbers make up the set of rational numbers?

Natural Numbers, Whole Numbers, and Integers are rational numbers.

Example: {1, 2, 3, -1, -2, -3}

Numbers with repeating decimals and terminating decimals are also rational.

Example: {2.34343434..., 3.45}

If a square root makes a perfect square, then it is rational.

Example: {√16, √100}

Hope this helps.

m=-3

Step-by-step explanation:

3-2(9+2m)=m

3-2(9)-2(2m)=m

3-18-4m=m

-15-4m=m

-15=m+4m

5m=-15

Divide by 5

5m/5=-15/5

m=-15/5

m=-3

To check if correct, subsitute m for -3 in the equation. And both sides of the equation must be equal

3-2(9+2m)=m

3-2(9+2(-3))=-3

3-2(9-6)=-3

3-2(3)=-3

3-6=-3

-3=-3
