\frac{ x+2 }{2} \cdot \frac{ 4x+20 }{x^2+6x+8 } \\\\x^2+6x+8\neq 0\\ \\x^2+4x +2x+8 \neq 0 \\ \\ x(x+4)+2(x+4)\neq 0\\ \\(x+4)(x+2)\neq 0

x+4 \neq 0 \ \ \wedge \ \ x+2\neq 0\\ \\ x\neq -4 \ \ \wedge \ \ x\neq -2 \\ \\ D=R\setminus \left \{ -4,-2 \right \}

\frac{ x+2 }{2} \cdot \frac{ 4x+20 }{x^2+6x+8 } =\frac{\not( x+2 )^1}{\not2^1} \cdot \frac{ \not4^2(x+5) }{\not(x+2)^1(x+4) } =\frac{2(x+5)}{x+4}

Write a formula that will compute the final grade for the course, using G to represent the final grade, H to represent the homew
Tasya [4]

Answer:

To calculate final grade we use the formula:

Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).

This formula help us to calculate the grade we need to get.

Step-by-step explanation:

Solution:

Suppose grade breakdown for certain college course is as follow:

Homework = 15%

Quizzes = 20%

Project = 10%

Test = 40%

Final exam= 15%

Let G represent the final grade

H represents homework average,

Q represents quizzes and P represent project, T represent test average and F represent final exam.

To calculate final grade we use the formula:

Final grade = H( the weight of h) + Q( the weight of q) + P (the weight of project) +T (the weight of test) + F(the weight of final exams).

This formula help us to calculate the grade we need to get.

Which of the following equations are equivalent to 2x(x - 2) = x? Select two that apply.
Verdich [7]

Answer:  C   2x(x - 2) - x = 0

 and <u>B</u>   2x² – 5x=0

Step-by-step explanation:

You get 2x(x - 2) - x = 0 by subtracting x from both sides of the original equation.

Then take 2x(x - 2) - x = 0 and distribute to get 2x² - 4x -x = 0

combine the x terma and you end up with 2x² – 5x=0
