<span>given:
bull's eye radius= x
width of surrounding rings=y
solution:
Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring
=Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
=Ď€(2xy+7y^2)
hence the area of the outermost ring in terms of x and y is π(2xy+7y^2).</span>
Answer:
A'(4,-5), B'(1,-6), C'(2,-3)
Step-by-step explanation:
Reflect across the line y = -1 to get these points. You can count how many points it takes to get to that line and then add the same amount of points to the other side.
