Answer:

Answer B is correct
Step-by-step explanation:


Answer:
(x-1)(x+6)
Step-by-step explanation:
=> 
<u><em>Using mid-term break formula to find it's factors</em></u>
=> 
=> x(x+6)-1(x+6)
Taking x+6 common
=> (x-1)(x+6)
As the archery target is a circular bull's eye then the radius you need to find is expressed by the following formula:
r = x + 4y
<span>After you have the radius, now you can find the area pf the outermost ring in the terms you need using the following formula
A = pi ( x + 4y )^2
I know you can get to the answer with this</span>
