Answer:

w = -5x^2+20x+160/x

Step-by-step explanation:

Divide both sides by x and since you can't divide -5(x-8)(x+4) by x, it becomes a fraction resulting the answer to be w = -5x^2+20x+160/x.

I may be wrong, it's been a while since I solved these types

How do you do equations involving factored expressions

Cerrena [4.2K]

Distribute the brackets to get all your terms and then combine like terms to simplify your expression.

(X+2)(x+2)
= x^2 + 2x + 2x + 4
= x^2 + 4x + 4

Y is the midpoint of XZ .X has coordinates (2, 4), and Y has coordinates (-1, 1). Find the coordinates of z.

cricket20 [7]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
X&({{ 2}}\quad ,&{{ 4}})\quad 
% (c,d)
Z&({{ x}}\quad ,&{{ y}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
\left( \cfrac{x+2}{2}~,~\cfrac{y+4}{2} \right)=\stackrel{Y}{(-1,1)}\implies 
\begin{cases}
\cfrac{x+2}{2}=-1\\\\
x+2=-2\\
\boxed{x=-4}\\
------\\
\cfrac{y+4}{2}=1\\\\
y+4=2\\
\boxed{y=-2}
\end{cases}$

The three types of qualitative research are phenomenological, grounded theory, and ethnographic research. Compare the difference

Crank

Answer with Step-by-step explanation:

There are three types of qualitative research are as follows:

1) Phenomenological

2) Grounded theory

3) Ethnographic research

Phenomenological is a method of explaining that exists as an integral part of the world.

For example, we all know very much about the 'counselors' but what does actually 'counselor' means?

Ethnographic research is the study of mankind that gives scientific description of individual human societies.

For example this type of research includes traditional anthropologic texts and it can be done by conducting interviews too.

Grounded theory is the theory that theory which is emerged from the data which is collected.

For example In this method, article is discussed theoretically and then use a visual mode to show how to use grounded theory.
