Answer:
1. You cannot divide by zero.
2. The inequality is equivalent to -20.2 > 0, which is false.

Step-by-step explanation:
they are not like terms because the term 9x^2 is to the 2nd power which means that you are supposed to times the number by itself 2 times and 9x is not to the 2nd power so it stays the same.
Sure, you can either simplify it further: 1/2 and you could also multiply by 2: 4/8
