Yes, slopes are easy, but with the problems my teacher is giving me- it seems to be hard. This is the question-
1) The coordinates for a quadrilateral are A (12,4), B, (8,12), C (-8,4), and D (-4, -4). What is the best description for the shape?

Choices: A-square B-Rectangle C-Rhombus D. General Quadrilateral

I did the problem and I got a AB-4 BC-17.9 CD-8.9 DA-17.9 If that is right, what shape should I pick If I only have two sides congruent and the other two not congruent and totally opposite. Did I do the problem right in the first place?

Something I always wondered when getting into and elevator. I've never gotten into one that has one of these fancy escape hatches overhead. Does any of the major manufacturers actually produce models with escape hatches. Or is this something that can be bought as an extra option. the expensive hatches overhead and the cheap ones underneath LOL
So is it just hollywood or do such elevators exist.

the first question on an examination paper is:

Solve for x the equation: 1/x = 1/a + 1/b

where (in the question) a and b are given non-zero real numbers. One candidate writes x = a + b as the solution. Show that there are no values of a and b for which this will give the correct answer.

I just can't seem to get a handle on them. Derivatives are a piece of cake, but integrals always seem to stump me. For example, I can't even integrate cos^3(x)sin(x)dx.
