Answer:
2(8x^2-13x+10)
Explanation:
There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.
Let's let A represent the measurement of one of the those angles in our pentagon.
The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.
But we are also given that this equals 40x^2-65x+50.
So that means 5A=40x^2-65x+50.
If we divide both sides by 5 we can find what one of our angles is in terms of x. So let's do that A=8x^2-13x+10.
So we want to know the sum of two our angles, we want to know what is A+A or 2A. 2A=2(8x^2-13x+10). To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

Answer:
The correct option is <u><em>D) These advancements are very expensive and not available to everyone.</em></u>
Explanation:
Consider the statement A. It states that the new technological advances uses renewable sources of energy. This is a positive aspect as the energy can be renewed and replaced. The corn from which this energy is derived can be produced over and over again. Hence, this is a positive aspect, not a negative aspect.
Consider statement B. This statement tells us that the new technological advances will not result in warming the Earth's atmosphere by greenhouse effect. Hence, it is a positive aspect.
Consider statement C. It states that the new technological advances will lead to lesser pollution. Hence, it is a positive aspect.
<u><em>Now, consider statement D. It is a drawback because technological advances are too expensive to be used by many people. Hence, it is a negative aspect.</em></u>
