Which equation correctly applies the distributive property? a. −1.2 ⋅ 0.57 ⋅ 0.5 = −1.2 ⋅ 0.5 ⋅ 0.57 b. 50 + 1.015 = (50⋅1) + (50 ⋅ 0.01) + (50 ⋅ 0.005) c. −2.5 ⋅ (4 ⋅ 1.045) = (−2.5 ⋅ 4) ⋅ 1.045 d.(0.5 ⋅ 0.5) + (0.5 ⋅ 0.3) + (0.5 ⋅ 0.2) = 0.5 ⋅ (0.5 + 0.3 + 0.2)

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! : )
