<u><em>Answer:</em></u>
\frac{8x}{x-5} which is option D

<u><em>Explanation:</em></u>
When multiplying fraction, we multiply the numerators by each other and the denominators by each other to get the final answer.

<u>The given expression is:</u>
\frac{x+2}{x-5} *  \frac{8x}{x+2}

<u>1- we multiply the numerators by each other and the denominators by each other. This will give us:</u>
\frac{(x+2)(8x)}{(x-5)(x+2)}

2- We can note that there is (x+2) common on both the numerator and the denominator. Therefore, <u>we will cross out this factor from both numerator and denominator. This will give us:</u>
\frac{8x}{x-5}

Since no further simplification can be done, therefore, our final answer would be \frac{8x}{x-5}

Hope this helps :)

umka21 [38]

Answer:

C.  They most likely used an observational study asking students to keep track of their TV habits and weight.

A.  This is an experiment because a treatment was applied to a group.

Step-by-step explanation:

According to our question:

1. The study concluded that there is a relation between watching TV and the weight gain in college freshmen.

Now, this is possible when a group of college students were asked to participate to watch TV for more than 1 hour for a specific amount of time and have a record of their weights.

So, the study is an observational study where the habits and weights of college students were observed.

Hence, option C is correct.

2. The students were divided onto two groups where one group used the computer program and the other did not to check the improvement in the reading levels.

This means that the students were given a procedure to follow during the study in order to see the results..

So, the study is an experiment where a treatment is applied to the group of students.

Hence, option A is correct.

Answer:

<h2>M(-a, b)</h2>

Step-by-step explanation:

Use the formula of a midpoint:

\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)

We have the points P(-2a, 0) and Q(0, 2b). Substitute:

x=\dfrac{-2a+0}{2}=\dfrac{-2a}{2}=-a\\\\y=\dfrac{0+2b}{2}=\dfrac{2b}{2}=b
