Y = 0:

0 is neither prime nor composite.
y=1:

3 is a prime number (because only 3 and 1 divide evenly into it)
y = 2:

8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)
Answer:
One is a = 2, b = 3 AND another one is a = 11, b = 12
Step-by-step explanation:
They all fit this description. b = 1+a
Smaller, since a half equals to 0.50
The answer is C. 100 because the total measure of a quadrilateral is 360. When you add up the 3 interior angle measures, it adds up to 260. Then you subtract 360-260 to get 100 as the fourth angle measure. Hope that this helped!
