The answer is b because 2S + L is equal to L + 2S.
An equation to model this scenario would be 2s=28, with "s" being the string.
<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:
The first one would be -30
The second one would be -20
The third one would be -10
The fourth one would be 0
The fifth one would be 10
