&#13;
Which of the following might be coordinates of the vertices of parallelogram ABCD?&#13;
A(0,0), B (a,0), C(a+b,c), D(b,c)&#13;
A(0,0), B(a,0), C(a,b), D (-a,b)&#13;
A(0,0), B(2a,0), C(a,b), D(-2a,b)&#13;
A(0,0), B(a,0, C(a-b,c), D(b,c)&#13;
&#13;
I would try to figure it out by plotting but values are mostly variables. And, even if I could plot it, there must be a short-cut pattern to spot parallelogram coordinates.Thanks in advance.&#13;

If the prisms are SIMILAR with LINEAR ratio of 3:2, what is the VOLUME of the smaller prism. Answer choices are 50, 56, 252, 126.&#13;
   Since the ratio of 3/2 is a LINEAR one rather than a volume one, I took the cubed root of 168 and got 5.517. Then I solved for x in a 3/2 ratio and got 3.678. Then I set up the ratio of 5.517 : 3.678 :: 3:2. That got me 112 which I was certain was the answer. But the above choices exclude 112. What am I doing wrong?

I am fouling up the algebra somehow, so I\\\'m not getting the same radius as the book I am working from. Here is the original problem:&#13;
&#13;
x^2 + y^2 + 4y + 2x - 20 = 0&#13;
&#13;
The book says I should get to the following step in the process of completing the square:&#13;
&#13;
x^2 + y^2 - 4y + 2y - 4 = 0&#13;
&#13;
But I just don\\\'t see where the -4y or the - 4 is coming from. &#13;
&#13;
I get the following next step instead:&#13;
&#13;
(x^2 + 2x + 1) + (y^2 - 4y + 4) = 20 + 1 + 4 &#13;
&#13;
This takes me to:&#13;
&#13;
(x + 1)^2 + (y - 2)^2 = 25&#13;
&#13;
then,&#13;
&#13;
25 = r^2&#13;
so r = 5&#13;
&#13;
But, I should be coming up with r = 3&#13;
&#13;
