To remove the parentheses, you just distribute.
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.
Answer: the mass of a neutron is approximately 2,000 times the mass of an electron
Step-by-step explanation:
- the easiest way to solve this (in my opinion) is to simply divide the mass of a neutron by the mass of an electron
- ![2 x10^{-24} / (9 x10^{-28} )](https://tex.z-dn.net/?f=2%20x10%5E%7B-24%7D%20%2F%20%289%20x10%5E%7B-28%7D%20%29)
= ![(2/9) x10^{-24--28}](https://tex.z-dn.net/?f=%282%2F9%29%20x10%5E%7B-24--28%7D)
= ![(2/9)x10^{-24+28}](https://tex.z-dn.net/?f=%282%2F9%29x10%5E%7B-24%2B28%7D)
≈ ![0.2222x10^{28-24}](https://tex.z-dn.net/?f=0.2222x10%5E%7B28-24%7D)
≈ ![0.2222x10^{4}](https://tex.z-dn.net/?f=0.2222x10%5E%7B4%7D)
≈ which is approximately 2222
- so 2222 is approximately 2000 times
- therefore, the mass of a neutron is approximately 2,000 times the mass of an electron
hope this helps :)

Answer: 2
Step-by-step explanation: That expression is a binomial in any case the terms in a polynomial are separated by a plus or minus sign (+,-) so you can determine the number of terms by counting how many number or variable are being separated (ex: 3a+a-1 would have 3 terms and be a trinomial)
