b.c.d.so your answer shoud be d.(Im assuming you mean n2 = 2n, but if you are trying to say n2 = n^2 {n squared} then your answer would be a.......
1.)Which of the following statements is(are) true for all positive integers?
1) 7n-2n is divisible by 5
2) n2+2n is divisible by 2
a. first statement is true
b. second statement is true
c. none are true
d. both are true

-
1) 7n-2n = 5n which is divisible by 5
2) n2+2n = 4n which is divisible by 2

so your answer shoud be d.

(I'm assuming you mean n2 = 2n, but if you are trying to say n2 = n^2 {n squared} then your answer would be a. because n^2 + 2n is not divisible by 2)
