Answer:
12 ....10....11....13 THATS THE CORRECT ORDER
Step-by-step explanation:
54 = 2(4x-3) + 2(x)
54 = 8x-6 + 2x
60 = 10x
6 = x
so two sides are 6 meters, and the other 2 sides are 21 meters
If it is the most common isotope and of Carbon and it is not an ion, you can conclude that it has 6 protons and 6 electrons.
