Answer:

5 & 10

Explanation:

x = integer, y= integer

We're given that they have a product of 50, meaning that when you multiply them they equal 50. So:


xy=50

It also gives us that one integer is twice the other:


x=2y

-You could do
y=2x or
x=2y , it doesn't matter

If I plug that in, I get:


2y^2=50


y^2=25


y=5, -5 or ±5

However! It says 2 positive integers so you would ignore the negative version

So
y=5, and
x=10
