Answer:
G
Step-by-step explanation:
Using the rule of exponents
= 
Consider the left side
=
, then
= n²
Since bases on both sides are equal, equate the exponents
x - y = 2 → G
Answer: -0.053
Step-by-step explanation:
1•(18/38) + -1 •(20/18) = -0.053
209/12 is 17.41, so 12 goes into 209 17 times.

x+6-x = 2x-x
6 = x
12:32 is simply 3:8 but divided by 4 to both sides.
