Mrs. Thornton asked her students to draw a figure with a perimeter of 4x + 4. Shown below are 4 drawings made by her students. (They are not drawn to scale.) Which one is NOT correct?

Find the value of the cosine for angle a

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142
