Answer 2

Answer:

correct answer

(1st )answer is even

(2d )The sum of two odd numbers is ..always even.

(3d)always an odd number

(4th)The product of two even numbers is even

Step-by-step explanation:

((1st)) explain " Since the sum of two integers is just another integer then we can let an integer n be equal to (x+y) . Substituting (x+y) by n in 2(x+y), we obtain 2n which is clearly an even number. Thus, the sum of two even numbers is even.

( 2d) explainTwo even numbers added together can be written as: 2n + 2m, where n and m are the even numbers in question, divided by two. ... Therefore, any even number plus any other even number will always equal an even number (as the answer you get will always be some number multiplied by two).

(3d)When two odd numbers are multiplied together, the result is always an odd number. Thus (n + 1)(m + 1) must be an odd number. Because n and m are even, when we multiply two even numbers together, we always get an even number. Thus nm is even.

(4th)'The product of two even numbers is even. The product of two even numbers is even. Let m and n be any integers so that 2m and 2k are two even numbers. The product is 2m(2k) = 2(2mk), which is even.
