The euro has depreciated and the dollar as appreciated
Answer:
I think first add the side 137+ 127 +118=382 / 382cm
D=12
Because if you write down the equation 4x-8=40 and plug in 12. 4 times 12 is 48
. 48-8 equals 40
Part a: subtract 48-30=18
Part b: i found it by subtracting 48 -30 because it says left over
