if a man can paint a room in m days and a woman can paint a room in w days how long will it take both of them to paint r rooms?

What advice would you give Matt and Cassey Topham who are building their £5million dream eco home in Nottinghamshire having won the euro lottery.

For example is a ten car garage actually big enough for the new-age eco warrior?

OK so maybe I'm dumb but can anyone explain to me logically why the vector equation

r.(6i + 4j - 2k) = 14 (which I got from vector a and vector n via a.n = r.n)

becomes the cartesian equation 3x + 2y -z = 7

I just can't get my head around it. (I don't just mean the factoring bit)

Don't misunderstand me - but no-one can live forever and the guy is way over the average life expectancy for that society. Wouldn't it be better just to pray for his peace and God's will in the matter?

A is point (-4,-6,3). The point P lies on straight line r = (2,-1,4) + t(1,3,1) and AP is perpendicular to that line. Find P.

Just can't seem to sort it but then I really don't quite get vectors yet. I must do a dot product somewhere and equate to 0 but can't get my two vectors. Help!

- I knocked her arm when she was putting her eyeliner on - how can I make amends?

up when I took her for a ride in my sports car. Did I do right.
