Let's say the Catholic population in France is 51,600,000 and the Muslim population is 8,400,000, the Muslim population currently grows at 2.3 percent a year, and the Catholic population grows at 0.03 percent per year, how do you find out what percent Catholic the population will be in the year 2100? Or what other information do I need, and how can I calculate it?

For the last 3 nights I have woken up at 11:11 pm. And since I can't sleep when it is quiet I play a CD. And everytime I wake up at 11:11 it is song number 11. It has been on a different CD evertime that this has happened. Is there some kind of meaning to this or am I being paranoid?????

a - b
-----------------------
a2 + 2ab - 3b2

plus

a + b
---------------------
a2 - 2ab - 3b2

a2 means a squared, b2 means b squared

The answer in my textbooks says:

2a
------------------------
(a - 3b)(a + 3b)

I don't how one would get that
Could someone show me?
Please and thanks

A) The question is [let u and v be vectors]:
prove that ||u+v||^2 + ||u-v||^2=2||u||^2+2||v||^2
and interpret the result geometrically by translating it into a theorem about parallelograms.

I went about proving the statement component wise, resulting in 2(u1)^2+2(u2)^2+ 2(v1)^2 + 2(v2)^2 = 2(u1)^2+2(u2)^2+ 2(v1)^2 + 2(v2)^2; however I don't know how to translate that into a theorem about parallelograms. Am I even attacking this problem in the correct manner?

B) Find the parametric equations for the line that is perpendicular to L1: x = 1 + 2t, y= 2-t, z=4-2t and L2: x= 9+t, y=5+3t, z = -4-t, and passes through their point of intersection

I found the point of intersection at (7, -1, -2) and I know that there is no y direction, but I cannot seem to find the x and z direction. Pretty much I need to find a and b in the following line but i do not know how.
x= 7 + At
y= -1
z= -2 + Bt

Any help on either would really be appreciated! Thanks!
