Answer:
6.5%
Step-by-step explanation:
If you take 31.20 and divide it by 480, you get .065, which would then be converted into percentages by multiplying it by 100 (6.5%).
Sqrt(x^16) is x^8.
As you can see, x^8 * x^8 = x*x*x*x*x*x*x*x * x*x*x*x*x*x*x*x which equals x^16

Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
