Alejandro reduced triangle a proportionally.

he made each side 1/2 as long.

use the drop-down menus to complete the statements below.

(1) Each side of triangle A is changed by a factor of 1/2.

(2) The unknown side length in triangle B has a measure of 7.5 units.

Step-by-step explanation:

It is given that Alejandro reduced triangle A proportionally.

It means triangle A and B are similar and their corresponding sides are proportional.

From the given figure it is clear that the side of length 12 units is reduce to 6 units.

Each side of triangle A is changed by a factor of 1/2.

Let the unknown side of triangle B be x.

On cross multiplication we get

Divide both sides by 2.

Therefore, the unknown side length in triangle B has a measure of 7.5 units.

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! : )
