Answer:

The rectangle is 11cm by 33cm long

Step-by-step explanation:

The easiest way to solve this is in a diagram, and that is how I'll explain the answer.

If you have a rectangle, where the length is 3 times the width, you can label the sides as x, and as 3x.

Now there are 2 sides labeled as 3x, and 2 sides labeled as x.

Since we are dealing with the perimeter of the rectangle, add all the values together to get 8x. since this value also represents the perimeter, we can set it equal to 88.

We then divide both sides by 8, to get x=11.

Then, plug in the value of x to each side,

So the width was x, and now is 11, and the length was 3x, and now is 33

Answer: The answers are in the photo. (They are color-coded.)

Step-by-step explanation:

A monarchy, democracy, and communism are different ways to run a government.

A monarchy is usually ruled by someone of royalty, like a king or queen. Typically, they inherit all the power and get to make all the decisions, whether their people like it or not.

In a democracy, the people have many liberties and rights. They get to vote for candidates that represent them that could get elected as a president, minister, mayor, etc. Those elected have to listen to what their people want.

In communism, the government gets to make all the decisions whether it benefits the people or not. This is runned by a single-party, meaning no other parties are allowed to be developed or run.

Answer:

(x- \frac{2}{5})^{2} = x^2 -\frac{4}{5}x + \frac{4}{25}

Step-by-step explanation:

You have two methods to expand this binomial.

Method 1  

If you have the expression:

(x- \frac{2}{5})^{2}

You can write the expression it in the following way:

(x-\frac{2}{5})^{2}=(x-\frac{2}{5})(x-\frac{2}{5})

Then, apply the distributive property:

(x-\frac{2}{5})(x-\frac{2}{5}) = x^2 -\frac{2}{5}x -\frac{2}{5}x+ (\frac{2}{5})\frac{2}{5}

Simplify the expression:

(x-\frac{2}{5})^2= x^2 -\frac{4}{5}x+ (\frac{4}{25})

---------------------------------------------------------------------------------------

Method 2

For any expression of the form:

(a-b)^2

Its expanded form will be:

(a-b)^2= a^2 -2ab + b^2

If

a = x

b =\frac{2}{5}

(x- \frac{2}{5})^{2} = x^2 - 2x\frac{2}{5} + (\frac{2}{5})^2

(x- \frac{2}{5})^{2} = x^2 -\frac{4}{5}x + \frac{4}{25}
