Answer: C: Euros
Step-by-step explanation: We know it is in euros because Germany has not branched off of the EU (European Union), it still uses euros, the currency of all of the countries in the EU.
I^22 equals to -1 since i^2 is negative one
9m+2=3m-10
subtract 3m from both sides to get:
6m+2=-10
subtract 2 from both sides to get:
6m=-12
finally, divide by 6 on both sides to get what m equals:
m=-2
