Positive,
because 2*12 equals to 24, and 24 is positive!
g(x) = 5^x is your answer
Plug in increasing numbers for x to get the output.
For example: when x = 1
f(1) = 5(1) = 5
g(1) = 5^(1) = 5
when x = 2
f(2)= 5(2) = 10
g(2) = 5^(2) = 25
when x = 3
f(3) = 5(3) = 15
g(3) = 5^(3) = 125
~
From the example above, we see that g(x) = 5^x is your answer

<span>width = x
</span><span>length = x+5
2x + 2(x+5) = 46
2x + 2x + 10 = 46
4x = 46 - 10
4x = 36
x = 36/4 </span><span>
x = 9 in </span> ← width
length = x+5 = 9 + 5 = 14 in
<span>
Area = 9 * 14 = 126 in</span>²<span>

5 kg is more precise because if you said 5212 g, they will be trying to see what the precise answer is so if you say 5 kg that will save all of the work.
P.S.: its not 5212 g, its 5000 g. :)
