### Re: Simplify n^2-81/(n+9)^2 by removing factors of 1

This is what I could do: n^2-81/(n+9)^2
factor numerator: (n-9)(n+9)
factor denominator: (n+9)^2

I'm stuck!

### How many days would it take space vehicle to reach Jupiter?

I need to find how many days it would take a space vehicle to reach Jupiter. It takes 3 days for a space vehicle to reach the Moon from Earth. The closest distance from Earth to the Moon is 240,000 mi. The closest distance from the Earth to Jupiter is 391,000,000 mi. How long would it take the space...

### N = 00.00006x^3 + 0.006x^2 - 0.1x + 1.7. To nearest million,

I need some serious help!

The number N, in millions, of hearing impaired persons of age X can be approximated by N= -0.00006x^3 + 0.0006x^2 - 0.1x + 1.7. Approximate to the nearest million the number of hearing impaired persons ages 35 and 50.
