= x·[2(x²- 4x + 4) + 3(x² + 6x + 9) - x² + 5x]

= x(2x² - 8x + 8 + 3x² + 18x + 27 - x² + 5x)

= x(4x² + 15x + 35)

Using the Distance Formula and the Pythagorean Theorem, find the distance, to the nearest tenth, from F (5,5) to G (−3,−1).
kvasek [131]

Answer:

<h2>The answer is 10 units</h2>

Step-by-step explanation:

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

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

where

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

From the question the points are

F (5,5) , G (−3,−1)

The distance between them is

|FG|  =  \sqrt{( {5 + 3})^{2} +  ({5 + 1})^{2}  }  \\  =  \sqrt{ {8}^{2}  +  {6}^{2} }  \\  =  \sqrt{64 + 36}  \\  =  \sqrt{100}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 10 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>10 units</h3>

Hope this helps you

If the values of the supplementary angles are 40 and 2x, what is the value of x? ANSWER QUICKLY PLS!​
Zolol [24]

Answer:

140°

Step-by-step explanation:

The value of supplement is 40 and X. We know that the sum of the sumplementary angles is 180. Therefore ,

=> x + 40° = 180°

=> x = 180° - 40°

=> x = 140°

<h3><u>Hence </u><u>the</u><u> </u><u>value </u><u>of </u><u>x </u><u>is </u><u>1</u><u>4</u><u>0</u><u>°</u><u> </u><u>.</u></h3>
