For the first one, I would complete the square for x ....put that on the left side....everything else on the right side you will ahve to 'massage' the R side so your equation looks like (x-h)^2 = 4p (y-k)
For the second one , remember the equation for standard form circle with center (h,k) is (x-h)^2 + (y-k)^2 = r^2
draw the rectangle.....find the center....that is h,k then the radius is given as r=60 , but it is a blueprint scaled so 40ft = 2 units (because the 800 ft dimension only goes to 40 units)
so r will be drawn as 3 units
Now can you do it?
