Answer:
negative reciprocal
Step-by-step explanation:
Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"
Suppose n is even. That means n = 2k where k is any integer.
Square both sides
n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)
The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even.
So this contradicts the initial statement which forces n to be odd.
Answer: 5 feet of wood for 2.23
because the unit rate for each foot of wood is .45 compared to getting 6 feet for 2.95. 2.23 plus .43 (the cost for one foot) would be 2.63 making the wood much cheaper than the 6 foot option.
