So, I think that you mean that
n²+m² is even? (the "plus" sign is missing, but I think this is correct).
this can only happen if either:
both n and m are even
or
both n and m are odd
That's because a sum of two expressions is even if either both or none of the expressions summed is even, and a power of a number is even only if the number is even too.
are those some of the options?
yes!
<span>n and m are even,- possible!
n and m are odd, -possible!
n+m is even, - possible; it would be the case i</span><span>f either both n and m are even or both n and m are odd n+m is odd,
so the option we'll choose is:
none of these are impossible </span><span />
This does not make sense, but with the logic, it would be B. Please comment to clarify so I can make changes if needed.
ANSWER: B
Is there supposed to be a picture?
Construct an equation in which s is the number of tons of sugar to be transported 4500 + 150.25s = 3696 + 200.5s Solve for s 4500 - 3696 = 200.5s - 150.25s 804 = 50.25s s = 804/50.25 = 16 tons of sugar The cost is found by plugging this value into either side of the original equation; it is $6904.
