O terreno da fazenda de Eduardo foi aumentado 2 m na horizontal e 2 m na vertical. Se antes do aumento o terreno tinha o formato

Novay_Z [31]

Answer:

New area of Eduardo's farm after the increase = x² + 4x + 4

Nova área da fazenda de Eduardo após o aumento = x² + 4x + 4

Step-by-step explanation:

English Translation

The land on Eduardo's farm was increased by 2 m horizontally and 2 m vertically. If before the increase the land was shaped like an x-side square, what is the new area after the increases?

Solution

The previous area of Eduardo's farm is the are of a square with side lenght of x.

Area of a square = (side length)² = x²

Then, the land on Eduardo's farm was increased by 2 m horizontally and 2 m vertically.

New horizontal length of Eduardo's farm = (x+2)

New vertical length of Eduardo's farm = (x+2)

New area of Eduardo's farm = (x+2)(x+2)

= x² + 4x + 4

In Portugese/Em português

A área anterior da fazenda de Eduardo é a de um quadrado com comprimento lateral de x.

Área de um quadrado = (comprimento lateral)² = x²

Em seguida, o terreno da fazenda de Eduardo foi aumentado 2 m na horizontal e 2 m na vertical.

Novo comprimento horizontal da fazenda de Eduardo = (x + 2)

Novo comprimento vertical da fazenda de Eduardo = (x + 2)

Nova área da fazenda de Eduardo

= (x + 2) (x + 2) = x² + 4x + 4

Find the measure of each acute angle in a right angle where the measure of one acute angle is 5 times the measure of the other a

lubasha [3.4K]

We are given that the measure of one acute angle is 5 times the measure of the other acute angle.

Let us assume the measure of the other acute angle = x degree.

First acute angle is 5 times the other, that is = 5x degrees.

Both angles are making a right angle.

A right angle sum upto 90 degrees.

Therefore,

x+5x = 90.

6x = 90.

Dividing both sides by 6, we get

x =15.

<h3>Therefore, other acute angle = 15° and one angle measure = 5 times of 15 that is 75°</h3>

I need an essay about the American dream

MariettaO [177]

I can get you a little bit :P

Most people, if not all in the US always want to live the American dream at some point in their lives. But the question is, what is the meaning of the American dream, and how can people achieve this vague and elusive realisation? The American dream is a national philosophy or a belief that specifies the ideal factors such as democracy, freedom, rights and equality that accords every citizen equal opportunity to prosper and achieve their set goals (Glenn, 2002). The foundation of the American dream is deeply rooted in the declaration of independence that assert that “all men are created equal”. In simple terms, the American dream eliminates the artificial barriers to prosperity and promotes upward social mobility for every individual in the US depending on their hard work irrespective of their, social, religious, historical and racial background. The American dream is a slogan that is selling across the globe and up to date we see millions of people crossing the American borders as immigrants in search of this dream that cannot otherwise be achieved in their homelands. The American dream is a reality as we see it through how different people in the US have developed and better their own ingenuity and achieve their goals through their best efforts. Making this dream a reality is not a straight path as it is all about overcoming the challenges which at the end of the day differentiates a resilient individual from the rest.

What is the slope of a line that is perpendicular to the line y = -x + 5?<br> N<br> N<br> N N

Andrew [12]

Answer:

slope=x

Step-by-step explanation:

The slope of a line that is perpendicular to another will have the negative reipricol of the first slope. For example:

-1/3 = 3

-6 = 1/6

4= -1/4

The equation is written in slope-intercept form:

y=mx+b

M is the slope. In the given equation, the slope is -x, which can also be written as -1x. The negative reipricol of -1x is 1x, or just x.

The slope of the perpendicular line is x.
