Answer:

x = 41

Step-by-step explanation:

\because \angle 1 \:\&\: \angle 2 \: are \: supplementary\\\therefore \angle 1 + \angle 2= 180°\\\therefore 3x°+ (2x-25)°= 180°\\\therefore 5x°-25°= 180°\\\therefore 5x°= 180°+ 25°\\\therefore 5x°= 205°\\\therefore x = \frac{205}{5}\\\huge \purple{\boxed {\therefore x = 41}}

Pls help me with this
LiRa [457]

Answer:

In this order from top to bottom, you get -12, -8, 0, 6, and 8

Step-by-step explanation:

You simply plug in the X value into each equation where it is needed.

So for the first one

2(-5)-2 = -10-2 = -12

2(-3)-2 = -6-2 = -8

2(1)-2 = 2-2 = 0

2(4)-2 = 8-2 = 6

2(5)-2 = 10-2 = 8

Find a polynomial with the following zeros. <br><br> HELPPPP ASAPPP
Pavlova-9 [17]

<u>Answer:</u>

x³ - 4x² + 2x + 4 = 0

<u>Here's how I solved this:</u>

<u>You start off by rewriting the zeros into factors:</u>

1 - √3    →    x = 1 - √3    →    (x - 1 - √3)

  2        →    x = 2           →    (x - 2)

1 + √3   →    x = 1 + √3   →    (x - 1 + √3)

<u>Now you want to multiply the factors together:</u>

     (x - 1 - √3) · (x - 2) · (x - 1 + √3)

<em>- Multiply the first two factors together -</em>

                (x - 1 - √3) · (x - 2)

                              ↓

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

 

<em>    - Combine like terms and simplify -</em>

    (x · x - x · 2 - √3 · x + √3 · 2 - x + 2)

                              ↓

          (x² - 3x - √3 · x + 2√3 + 2)

<em>       - Now multiply the third factor -</em>

   (x² - 3x - √3 · x + 2√3 + 2)(x - 1 + √3)

                              ↓

(x² · x + x² · √3 - x² - 3x · x - 3x · √3 + 3x - √3 · xx - √3 · x · √3 +√3 · x + 2 · √3 · x + 2 · √3 · √3 - 2 · √3 + 2x + 2 · √3 - 2)

                              ↓

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

<em>    - Combine like terms and simplify -</em>

(x³ + x² · √3 - x² - 3x² - 3x · √3 + 3x - √3 + 3x - √3 * x² - x · 3 + √3 · x + 2 · √3 · x + 2 · 3 - 2 × √3 + 2x + 2 √3 - 2)

                              ↓

                 x³ - 4x² + 2x + 4

--------------------------------------------------------------------------------------------------------------

And there we get our solution: <u>x³ - 4x² + 2x + 4</u>
