Quadrilateral ABCD is shown. Quadrilateral A B C D . Side A B has a length 2 y plus x, side B C has length 5 x plus 4 y, side C D has length 3 y plus 5, and side D A has length 7 x minus 2. Angle A B C has measure 55 a minus 3 degrees and opposite angle C D A has measure 4 a plus 9 degrees.

What must the values of m and n be for ABCD to be a parallelogram?

step-by-step explanation:

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! : )
