Answer 1

Answer:

hi mate

Step-by-step explanation:

if p is any positive number then 2p will be a positive number .for ex: if p is 4

2p will be 2*4=8 another example is if p is 5 then 2p will be 5*2 which is 10.then 2p-2 will also be an even number as any even number is subtracted by even number gives even number.therefore every even number is divisible by 2.therefore 2p-2 will be divisible by 2.
