Using the Pythagorean theorem:
x^2 + (x-2)^2 = (√20)^2
Simplify the right side:
x^2 + (x-2)^2 = 20
Subtract 20 from both sides:
x^2 + (x-2)^2 - 20 = 0
Factor:
(x-4)(x+2) = 0
Solve for each x:
x = 4 and x = -2
The side cant be a negative value, so the answer would be x = 4
The answer is B.
The correct answer is: [C]: " (0, 24) " .

Given the quadratic function:
___________________________________________________________
→ " y = (x <span>− 8) (x + 3) " ; </span>← Note: Replace the "f(x)" with: "y" ;
→ Find the "y-intercept".
___________________________________________________________
→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .
→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;
→ " y = (x − 8) (x + 3) " ;
→ y = (0 − 8) (0 + 3) ;
→ y = (-8) * (3) ;
→ y = - 24 ;
___________________________________________________________
So, the "y -intercept" of the <em><u>given</u></em> quadratic function is:
the point at which: "x = 0 ; y = -24 " ;
→ that is; the point the coordinates: " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .

Answer:
its 34
Step-by-step explanation:
its half of the center angles
The equation that represents the array (rectangles and area) multiplication model that sows two grey shaded columns of length one ninth each and three rows with dots of width one fourth each is option <em>a</em>
a) The equation with fractions two ninths times three fourths is equal to six thirty sixths
![\dfrac{2}{9} \times \dfrac{3}{4} = \dfrac{6}{36}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B9%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B4%7D%20%3D%20%5Cdfrac%7B6%7D%7B36%7D)
<h3>What is an array (area) multiplication model?</h3>
An array representation of a multiplication is a rectangular visual order of positioning of rows and columns that indicates the terms of a multiplication equation.
Please find attached the area model to multiply the fractions
The terms of the equation represented by the model are indicated by the two columns of length one ninth each shaded grey and the three rows of width one fourth each covered with dots, such that the equation can be presented as follows;
![\left(\dfrac{1}{9} +\dfrac{1}{9}\right) \times \left(\dfrac{1}{4} +\dfrac{1}{4} + \dfrac{1}{4} \right) = \dfrac{2}{9} \times \dfrac{3}{4} =\dfrac{6}{36}](https://tex.z-dn.net/?f=%5Cleft%28%5Cdfrac%7B1%7D%7B9%7D%20%2B%5Cdfrac%7B1%7D%7B9%7D%5Cright%29%20%5Ctimes%20%5Cleft%28%5Cdfrac%7B1%7D%7B4%7D%20%2B%5Cdfrac%7B1%7D%7B4%7D%20%2B%20%5Cdfrac%7B1%7D%7B4%7D%20%5Cright%29%20%3D%20%5Cdfrac%7B2%7D%7B9%7D%20%5Ctimes%20%5Cdfrac%7B3%7D%7B4%7D%20%3D%5Cdfrac%7B6%7D%7B36%7D)
The equation that the model represents is therefore;
- The equation with fractions two ninths times three fourths is equal to six thirty sixths

Answer:
Angle 1: 168
Angle 2: 12
Explanation:
I did the math! basically, i did 168-156, and got 12. Then i added, 168+12, and got 180. So i know that both angles together make 180 degrees, which is the definition of supplementary angles.
