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.

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
