Answer:

f(x) = x² - 9x + 18

General Formulas and Concepts:

Algebra I

Standard Form: ax² + bx + c = 0
Binomial Roots: (x + a)(x + b)(x + c)(x + ...)
Expanding by FOIL-ing (First, Outside, Inside, Last)

Step-by-step explanation:

Step 1: Define

Zeros/Roots x = 3, 6

Step 2: Find Function

Rewrite Binomial Roots: f(x) = (x - 3)(x - 6)
Expand by FOIL-ing: f(x) = x² - 6x - 3x + 18
Combine like terms (x): f(x) = x² - 9x + 18

Actually Welcome to the Concept of the Similarities.

Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,

hence for,

1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3

hence the value of x is 12 , ===> x = 12 .

2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,

hence we apply the relation,

x = 2*4.5 ===> x = 9 units.

Find the length of the arc.

Arte-miy333 [17]

radius=r=7in
Angle=135°

We know

Length if arc=L

$\boxed{\sf L=\dfrac{\theta}{360}\times 2πr}$

$\\ \sf\longmapsto L=\dfrac{135}{360}\times2π(7)$

$\\ \sf\longmapsto L=\dfrac{27}{72}\times 14π$

$\\ \sf\longmapsto L=\dfrac{27}{36}\times 14π$

$\\ \sf\longmapsto L=\dfrac{9}{12}\times 7π$

$\\ \sf\longmapsto L=\dfrac{63π}{12}$

$\\ \sf\longmapsto L=\dfrac{21π}{4}in$
