Figure abcd has vertices a(−2, 3), b(4, 3), c(4, −2), and d(−2, 0). what is the area of figure abcd?

If 1/2 is half of 1, what is 1/2 of 2,3, and 4?

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
