these numbers form an addition and subtraction fact family 8,3,11 choose the fact family formed by these numbers the choices are a 8+3=11 11-3=8 b 8-3=5 11-3=8 11+8=19 11+3=14 c 11-8=3 11-3=8 11+3=14 c 11-8=3 11-3=8 11+3=14 11+8=19 d 3+8=11 8+3=11 11-8=3 11-3=8 is it abc or d what is the answer

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! : )

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
