Cindy has 500 feet of fencing to build a rectangular enclosure for her chickens. The enclosure has a a width of a feet a length of b feet an the perimeter is represented by the equation 2(a+b)=500. Part A suppose Cindy changes the width of the rectangular enclosure. Solve the equation for b to see how the new length will be affected. Show work Part B Cindy changes her mind and decides to purchase an additional 150feet of fencing. Instead of changing the width she instead wants to see how the width is affected by changing the length. Solve the equation for a and show work. Part C explain how to solve an equation for a particular variable if the equation consists of mostly variables and very

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
