Select all the choices below that show three lengths that could be the lengths of a triangle? 2 cm, 3 cm, 8 cm
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in

The last three,

2 cm, 5 cm, 6 cm

4 cm, 8 cm, 11 cm

10 in, 5 in, 13 in

As long as any two sides added together are long than the third side, it works as a triangle!

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! : )
