Find the perimeter of quadrilateral ABCD. Round to the nearest tenth. 4 in T M N 1 OA x 1 2 3 4 5​

answer: (1,3) and (-2,0) i think.

the first one, all those points on the line just make a strait line.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
