Asha makes a conjecture that the perimeter of a square whose sides are an odd
integer is always even. Which choice is the best proof of her conjecture?
CLEAR
CHECK
Every time you add four odd numbers, the sum is an even
number.
Let m and n both represent odd numbers that are the side
lengths of a square. And let m +n be an even number.
Therefore, m+n=n+m, which shows that the sum
of two odd numbers is even. And if two odd numbers are
even, then four odd numbers are also even.
Let n be an odd number. Because 4n is a multiple of 2, it
is an even number.
Look at these different examples: 5+5
9+9+9+9= 36. So if the side of a square is add,
the perimeter must be even.
