Y = 0:

0 is neither prime nor composite.
y=1:

3 is a prime number (because only 3 and 1 divide evenly into it)

Answer:
Step-by-step explanation:
49b² - 81 = (7b)² - 9 ²
by identity : 49b² - 81 = (7b - 9)( 7b + 9)
There are 20 boys in the class. The ratio is 4:3 so that means 4 out of 7 are boys and 3 out of 7 are girls. Divide 35 by 7 and you get 5. 5 times 4 is 20. 5 times 3 is 15. add them together and you have 35 students in total. So 20 students are boys and 15 students are girls.
