16. A rectangle of length (4x - 1) cm and breath 2xcm has an area of 10cm2. Find
a Value of x
b. Its length and breath
c. Perimeter​

Answers

Answer 1
a) 2x(4x-1)=10

Expand

8x^2-2x=10

Divide all terms by 2

4x^2-x=5

4x^2-x-5=0

4x^2+4x-5x-5=0

4x(x+1)-5(x+1)=0

(4x-5)(x+1)=0

x is equal to -1 and 5/4

but, in this case, the side of a rectangle cannot be negative, so the only answer that is mathematically possible is 5/4

b) substitute 5/4 into given expressions

length: 4(5/4)-1 which is 4cm

width: 2*5/4 which is 2.5cm

c) plus all four sides together

2.5+2.5+4+4 which is 13cm

How do we know Lauren lives in a dystopian future? "Octavia E. Butler Parable of the Sower"

Answers

Answer:

The setting of the story is in the 2020s where the protagonist Lauren, an African American girl lives with her family in a gated community. And we can know it is a dystopian world, for the world then is full of suffering, self-interest, drugs specifically designed for a particular purpose, the rise in crime, and authoritarian power, etc.

Explanation:

Octavia E. Butler's dystopian novel "Parable of the Sower," tells the story of Lauren Olamina, an African American girl in the 2020s. This futuristic novel deals with themes of dystopian ideals, where self-interest, conflicting interests, and various crimes overtakes the world community.

Dystopian worlds are where societies are confined within themselves, an imagines space where injustice or suffering is abundantly found, oppressive societal control, the lack of democracy which is replaced by an authoritarian, totalitarian power-hungry individuals. One factor that helped us understand or know the dystopic world Lauren is in is through the details such as increased crime rates, the rise in gated communities, designer drugs, illiteracy, etc.

Answers

Answer:

These characters, known as foil characters, are Gabriel, Lyons, and Bono. I believe the most important foil character in this play is Bono. Bono, from his very first introduction, seems to be a carbon copy of Troy. The act the same, speak the same, work the same job and enjoy the same past times.

Explanation:

Troy criticizes Rose's enjoyment of playing numbers, a game like the lottery that Lyons also enjoys. Troy displays his sense of responsibility in his reaction to Rose's hobby, but simultaneously provides evidence of his selfish treatment of Rose.

Read the excerpt from “A Genetics of Justice” Which statement best analyzes how the author develops the central idea across the paragraphs?

Answers

Answer:

The correct answer is Alvarez explains that, although her parents reacted differently to the stress they endured, both became silent about the dictatorship.

Explanation:

This question is incomplete. Here are the excerpt and the options missing:

My mother, especially, lived in terror of the consequences of living as free citizens. In New York City, before Trujillo was killed, Dominican exiles gathered around the young revolutionary Juan Bosch planning an invasion of the Island. Every time my father attended these meetings, my mother would get hysterical. If the SIM found out about my father's activities, family members remaining behind were likely to be in danger. Even our own family in New York could suffer consequences. Five years earlier, in 1955, Galindez, an exile anti-Trujillo teaching at Columbia University, had disappeared from a New York subway. The same thing could happen to us.

I don't know if my father complied or just got too busy trying to make a living in this country. But after a few months of hotheaded attendance, he dropped out of these political activities and his silence deepened.

Which statement best analyzes how the author develops the central idea across the paragraphs?

Alvarez explains that her parents often disagreed about how to react to the dictatorship now that they were living in a free country

Alvarez explains how her father became heavily involved in anti-Trujillo activities, but soon became too busy to participate in them.

Alvarez explains how her mother eventually convinced her father to stop attending political meetings because of the danger.

Alvarez explains that, although her parents reacted differently to the stress they endured, both became silent about the dictatorship.

 As the excerpt clearly says: "his silence deepened."

Alvarez tells the horrible things that happened because of the dictatorship, and even that he could happen to her parents and her family.

However, despite the stress of not knowing what would happen to their lives, both parents were silent about the dictatorship.

How does the narrator feel about the space trip in "Octavia E. Butler Parable of the Sower"

Answers

Answer:

The narrator feels positive about space travel, since this is portrayed as something beneficial for humanity.

Explanation:

In this story we meet Lauren, a girl who lives in the middle of a destroyed society and completely without resources. In this story, the world is no longer as we know it and life is very difficult, in addition, the difficulties that humans experience causes polarization and persecution of religious and social minorities. This all makes Lauren worried about the human, but she believes that humans can do more than that and that it is the duty of the human being to travel outside the pallet and achieve improvements for their survival. Since space travel is portrayed as something beneficial for the protagonist, the narrator follows this reasoning and is positive about it.

Do you watch TV commercials? According to the Television Research
Council, average teenagers will have spent 175,000 hours watching
over 350,000 commercials by the time they graduate from high school.
Now a new study has shown that watching commercials increases
behaviors linked to greed, selfishness, and irresponsibility. Due to
overexposure to advertisements, many teens may be making poor life
choices
O A. TV stations play too many commercials during teen programming
OB. Teens watch too much television and too many commercials,
C. The Television Research Council suggests limiting the amount of
TV a teen watches.
D. Commercials are having a negative effect on today's teens.

Answers

Answer:

D. Commercials are having a negative effect on today's teens.

Explanation:

The main focus of the paragraph is talking about TV commercials and its effects on teens. It gives a statistic on how many commercials teens have watched before graduating. Then, it goes into stating things about its effects "...a new study has shown that watching commercials increases behaviors linked to greed, selfishness, and irresponsibility." This directly correlates to option D. It is showing how commercials persuade teens to make more "poor life choices."

A is incorrect because the paragraph is not directly addressing TV stations. There isn't even the word "stations" mentioned anywhere in the paragraph.

B is incorrect because even though this is true, the paragraph doesn't talk about how much TV teens watch, it talks about commercials. Even then, that is not what the paragraph is aiming at.

C is incorrect because nowhere did it say that The Television Research Council suggests to limit the amount of TV they watch. Once again, this isn't about TV, it is about commercials.

This leaves option D as the correct answer.

I hope this helps!!
