D . A cube that is 1 inch long , 1inch wide and 1 inch high .

Answer
its a cube whose side is 1 unit long .
And total surface area should be 6 square units .
as we can see
There are many pairs of integers (whole numbers) that equal -6.
1 + 5
2 + 4
3 + 3
-3 + 9
You can choose from any of those pairs.
X/(x+5) = (x-2)/(x+1)
x(x+1) = (x -2) (x + 5)
x^2 + x = x^2 - 2x + 5x - 10
x = 3x - 10
3x - x = 10
2x = 10
x = 5
answer is A
5
