Which of the following statements correctly illustrate the addition property of equality?

check all of the boxes that apply.

if a = b, then a + c = b + c.

if x = y, then x + 2 = y- 2.

if w + 2 = 7, then w + 2-2 = 7- 2.

if z-mr001-1.jpg=9,then z-mr001-2.jpg+mr001-3.jpg=9-mr001-4 .jpg.

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
