Step-by-step explanation:
We can use the distributive property to simplify this expression.
I split this up into different parts--it helps me visualize better.
To begin, "-2m(m + n - 4)" becomes "-2m^2 - 2mn + 8m"
Then, "5(-2m + 2n)" becomes "-10m + 10n"
Finally, "n(m + 4n - 5)" becomes "mn + 4n^2 -n"
We can then simplify even further by combining like terms. The final expression is: C
Hope this helps!

Step-by-step explanation:
Counting the check digit, there are 12 digits, so this is a GTIN-12 code. Alternate digits are multiplied by 3 and the result summed with the sum of the other digits. The check digit is the amount required to make this sum be a multiple of 10.
(4 +9 +0 +0 +7 +2)·3 +(8 +0 +0 +3 +8) = 66+19 = 85
The check digit is 5, the number that must be added to this to make the total 90, a multiple of 10.
