The equation would be (53.50-17.50)<span>÷4 because we need to subtract the potting soil, and since there are 4 shrubs, then you need to divide to get the total of one shrub. It could also be (s=shrubs) 4s + 17.50 = 53.50 and then solve for s. Now, let's solve it. 53.50-17.50=36. Now, divide 36 by 4, to get 9. So, each shrub cost $9. Hope this helped!</span>
The formula for a circle is (x - h)^2 + (y - k)^2 = r^2 Where (h, k) is the center and r is the radius. x^2 + (y - 8)^2 = 25 25 = r^2 So the radius is sqrt 25 or 5. Radius = 5
