Question

6. Let x and y be positive integers such that x is prime and y is composite then which ofthe following true ? 1)y-x can't be even 2)xy can't be even 3)x+y/x can't be even 4)none​

Answer 1

Answer:

none

Step-by-step explanation:

if the x is a prime number and y is a composite number then x=2, y=4

1. (4-2)=2 which is an even integer

2.(2×4)=8 which is an integer

3.(2+4)/2=4 which is an integer

so the answer is none.
