The law of conservation of matter basically states that matter can’t be created or destroyed, only changed in form, so you can rule out any option that mentions destroying or creating matter. That leaves only option A. Atoms cannot be created or destroyed by chemical reactions.
transverse wave
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
Answer:The product of the given expression is :![n^2+6n-16](https://tex.z-dn.net/?f=n%5E2%2B6n-16)
Explanation:
Given expression:(n + 8)(n - 2)
Using identity: ![(a+b)(a+c)=a^2+(b+c)a+bc](https://tex.z-dn.net/?f=%28a%2Bb%29%28a%2Bc%29%3Da%5E2%2B%28b%2Bc%29a%2Bbc)
a = n, b=8, c= (-2)
![n^2+(8+(-2))n+(8)(-2)](https://tex.z-dn.net/?f=n%5E2%2B%288%2B%28-2%29%29n%2B%288%29%28-2%29)
![n^2+6n-16](https://tex.z-dn.net/?f=n%5E2%2B6n-16)
The product of the given expression is :![n^2+6n-16](https://tex.z-dn.net/?f=n%5E2%2B6n-16)
