Answer:

$lenght= 6 {x}^{2} + 4x - 3$

Step-by-step explanation:

$lenght = \frac{area}{width} \\ \\ = \frac{36 {x}^{3} + 24 {x}^{2} - 18x }{6x} \\ \\ = \frac{6x(6 {x}^{2} + 4x - 3) }{6x} \\ \\ lenght= 6 {x}^{2} + 4x - 3$

Curtis plays a trivia game he earns 2 points for each correct answer and loses 0.25 points for each incorrect answer he get 21 c

Maslowich

Answer:

Step-by-step explanation:

Curtis is playing a trivia game.

Number of points earned for each correct answer = 2

Number of points lost for each correct answer = 0.25

Given that:

Number of correct answers given by Curtis = 21

Number of wrong answers given by Curtis = 4

To find:

Total score of the game by Curtis?

Solution:

First of all, let us find the points earned by correct answers.

Points earned by correct answers = Number of correct answers multiplied by Points earned on one correct answer.

Points earned by correct answers = 21 $\times$ 2 = 42

Now, let us find the points to be lost by wrong answers.

Points lost by wrong answers = Number of wrong answers multiplied by Points lost on one correct answer.

Points lost by wrong answers = 4 $\times$ 0.25 = 1

The score of the game can be calculated by subtracting the points lost from the points earned.

Score = 42 - 1 = <em>41</em>

Line CH contains points (-2, 6) and H(5, -3) What is the slope of G?

Xelga [282]

Answer:

The slope of line G is $\dfrac{- 9}{7}$ .

Step-by-step explanation:

Given as :

The points of the line CH contains

C = $x_1$ , $y_1$ = - 2 , 6

H = $x_2$ , $y_2$ = 5 , -3

Let The slop of line CH = G

<u>Now, slope of line is </u>

G = $\dfrac{y_2 - y_1}{x_2-x_1}$

i.e G = $\dfrac{- 3 - 6}{5 -(-2)}$

Or, G = $\dfrac{- 9}{5 +2}$

Or,G = $\dfrac{- 9}{7}$

So, The slope of the line CH = G = $\dfrac{- 9}{7}$

Hence, The slope of line G is $\dfrac{- 9}{7}$ . Answer
