The equation that models the difference in the projected enrollments for
public schools and private schools as a function of the number of years
since 1985 is B - R = (-18.53t^2 + 975.8t + 48140) - (80.8t + 8049) = -18.53t^2 + 975.8t + 48140 - 80.8t - 8049 = -18.53t^2 + 895t + 40091
12 x g + 1
Hope this help you
Answer:
![x^6+3x^3+3+\dfrac{1}{x^3}](https://tex.z-dn.net/?f=x%5E6%2B3x%5E3%2B3%2B%5Cdfrac%7B1%7D%7Bx%5E3%7D)
Step-by-step explanation:
We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that
![(x^2 + \dfrac{1}{x})^3=(x^2)^3+3(x^2)^2\dfrac{1}{x}+3x^2(\dfrac{1}{x})^2+(\dfrac{1}{x})^3\\\\=x^6+3x^4\dfrac{1}{x}+3x^2\dfrac{1}{x^2}+\dfrac{1}{x^3}\\\\=x^6+3x^3+3+\dfrac{1}{x^3}](https://tex.z-dn.net/?f=%28x%5E2%20%2B%20%5Cdfrac%7B1%7D%7Bx%7D%29%5E3%3D%28x%5E2%29%5E3%2B3%28x%5E2%29%5E2%5Cdfrac%7B1%7D%7Bx%7D%2B3x%5E2%28%5Cdfrac%7B1%7D%7Bx%7D%29%5E2%2B%28%5Cdfrac%7B1%7D%7Bx%7D%29%5E3%5C%5C%5C%5C%3Dx%5E6%2B3x%5E4%5Cdfrac%7B1%7D%7Bx%7D%2B3x%5E2%5Cdfrac%7B1%7D%7Bx%5E2%7D%2B%5Cdfrac%7B1%7D%7Bx%5E3%7D%5C%5C%5C%5C%3Dx%5E6%2B3x%5E3%2B3%2B%5Cdfrac%7B1%7D%7Bx%5E3%7D)
36 divided by 3 plus 90 divided by 3 I think I hope this helps u
