Answer 1

Answer:

Step-by-step explanation:

Heyo!

As u can see x=28 +(t*2)   which means its 28+even no.

29 is the next prime no after 28  nxt is 31 for all of these, an odd no is to be added to get a prime no... but u r adding a even no.

so x is a composite no.

lets see Y..

y=17+(s*2)   which means its 17+ even no.

19, 23 are next prime no, just saying dor refference, u can check all next prime numbers too, to get to them an even no should be added ..u r adding a even no.

so y is a prime no.

now x-y = 11+(even no. - even no. )  = 11+even no.  == prime no.

likewise x+y =45+(even no. + even no.) = 45+ even no. == primeprime no

so 1, 2, 3  are correct.
