Answer:
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
![\dfrac{b-3a}{bc^{2}-d}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D1)
Step-by-step explanation:
Evaluate:
![\dfrac{b-3a}{bc^{2}-d}](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D)
When a=-4, b=2, c=-3, and d =4
Solution:
Substitute, a=-4, b=2, c=-3, and d =4 in above expression we get
![\dfrac{b-3a}{bc^{2}-d}=\dfrac{2-3(-4)}{2(-3)^{2}-4}\\\\=\dfrac{2+12}{18-4}\\\\](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D%5Cdfrac%7B2-3%28-4%29%7D%7B2%28-3%29%5E%7B2%7D-4%7D%5C%5C%5C%5C%3D%5Cdfrac%7B2%2B12%7D%7B18-4%7D%5C%5C%5C%5C)
![\dfrac{b-3a}{bc^{2}-d}=\dfrac{14}{14}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D%5Cdfrac%7B14%7D%7B14%7D%3D1)
Therefore, the variable expression when a=-4, b=2, c=-3, and d =4 is
![\dfrac{b-3a}{bc^{2}-d}=1](https://tex.z-dn.net/?f=%5Cdfrac%7Bb-3a%7D%7Bbc%5E%7B2%7D-d%7D%3D1)
You must first simplify the radicals by taking out any perfect squares.
√8 + 3√2 + √32 =
√4 * √2 + 3√2 + √16 * √2 =
2√2 + 3√2 + 4√2 =
9√2
Answer:
Ok say your social life is on that scale, Now the moment you walk into school your life is A which means it hasn't made it anywhere..now as you progress your love life goes up and becomes a B soon you grow popular and hit C as your results sky rocket..suddenly something you do affects that maybe a bad grade or something you did to someone then your social life drops dramatically to a D and soon crumbling to an E.
