Answer:

-x² + x + 6

Step-by-step explanation:

Hey there!

To solve this, you have to use foil...

( 3 - x ) ( x + 2 )

3 ( x + 2 ) = 3x + 6

-x ( x + 2 ) = -x² - 2x

3x + 6 - 2x - x²

-x² + x + 6

Hope this helps :)

Consider the following pair of points.
dedylja [7]

Answer:

The answer is

<h2>\sqrt{265}  \:  \: or \:  \:  16.28 \:  \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(9,-8) and (-7,-5)

The distance between them is

d =  \sqrt{ ({9 + 7})^{2}  +  ({ - 8 + 5})^{2} }  \\  =  \sqrt{ {16}^{2} + ( { - 3})^{2}  }  \\  =  \sqrt{256 + 9}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{265} \:  \:  \:  \:  \:  \:    \\  = 16.27882

We have the final answer as

\sqrt{265}  \:  \: or \:  \:  16.28 \:  \:  \:  \: units

Hope this helps you

X-27 = 7x -15<br><br> please show the work, i’ll mark brainliest
qaws [65]

Answer:

x=-2

Step-by-step explanation:

x-27 = 7x -15

subtract x from both sides

-27=6x-15

add 15 to both sides

-12=6x

divide both sides by 6

-2=x

x=-2
