Evaluate y^2 + 2y for y = 0, 1, and 2. Are the resulting numbers prime or composite.

Elza [17]

Y = 0:
$(0)^2+2(0)=0+0=0$
0 is neither prime nor composite.

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

y = 2:
$(2)^2+2(2)=4+4=8$
8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)

As we can notice the shape is a Pentagon. A Pentagon's angles should add up to 540. So we can use simple addition and subtraction to solve.

121 + 108 + 102 + 100 = 431

540 - 431 = 109

109 should be your answer
