Answer:
A
Step-by-step explanation:
The sum of the exterior angles for each polygon is always 360°.
The sum of the interior angles for each polygon is always 180°(n-2).
If you have n-sided convex polygon, then

So,

With the first problem: You always divide from the left, then the rigth. 2+246/6 = 246/6=41 41+2=43
4^x+3 (the x + 3 is included in the power). That's just another way that you could write that.
If you are using half as much milk every day, you'll never run out because you'll just keep using half as much. You still won't run out with the coffee shop problem or the refrigerator problem.
