x is 20

Step-by-step explanation:

x = 5

Step-by-step explanation:

The 2 triangles are similar by the AA postulate then the ratios of corresponding sides are equal , that is

=

= ( cross- multiply )

30(2x + 10) = 40(x + 10) ← distribute parenthesis on both sides

60x + 300 = 40x + 400 ( subtract 40x from both sides )

20x + 300 = 400 ( subtract 300 from both sides )

20x = 100 ( divide both sides by 20 )

x = 5

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.
