Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show you how to answer a similar question.

We can say that polygons are similar if they have the same shape but not necessary same size. Also their corresponding angles are equal, while their corresponding sides are proportional.

From the image attached, we can see the lengths of the sides, hence we can find the values of x.

\frac{JN}{AE}=\frac{LM}{CD}\\  \\\frac{4.8}{4}=\frac{x}{3}\\  \\1.2=x/3\\\\x=3.6

How can i solve this<br> (x+2)(2x+3)<br> step by step please
MrRissso [65]

Answer:

2x² + 7x + 6

Step-by-step explanation:

To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).

You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.

(x+2)(2x+3)

2x²+ 3x + 4x + 6

2x² +7x + 6

Which graph represents an equation in the form =?<br><br> Please help me!!
Genrish500 [490]

That's a question about graphs.

In the Cartesian coordinate system, we have two axes: The x-axis (horizontal) and the y-axis (vertical).

When we want to represent a equation in the cartesian coodinate system, we associate a point in the x-axis and other in the y-axis. The Cartesian coordinate is represented by (x, y).

To represent some equation in a graph, we need at least two points to draw a line that cross these 2 points.

For example: To represent the equation y  = x +1, let's replace the value of <em>x</em>:

  • When<em> x = 0</em> → y = 0 + 1 = 1. Therefore, the coordenate is (0, 1).
  • When <em>x = 1</em> → y = 1 + 1 = 2. Therefore, the coordenate is (1, 2).

Finally, if we draw a line tha cross these 2 points, we will have the graph that represents y  = x +1.

Now you know about it, let's solve our problem?

In that question, we should to find the graph that represents the equation y = kx, but we don't know the value of <em>k</em>, so what should we do? It's easy:

<em>k </em>is a constant. That means that the value of k never changes. Now, let's analyze a specific case:

If <em>x = 0</em>, so <em>y = 0</em> as well. But why? We know that any number multiplied by 0 is equal 0. Therefore:

  • When If <em>x = 0 → </em>y = 0 \times k = 0. So, this graph cross the coordinate (0,0).

With the informations that the problem give to us, these are the unique things that we can find, but that's enough.

When we look at the options, just the second graph have a line that cross the coordenate (0, 0). Therefore, the correct answer is the graph below:

I hope I've helped. :D

How important are fair housing laws?
Vesna [10]

The reason why these laws are so important is that housing plays a major role in defining a person’s quality of life and is fundamental to our success. Our homes guarantee our family’s security, ensure our personal contentment, and dictate our connection to community and access to opportunities. Where a person lives affects their social, cultural, educational and many other community amenities such as: schools, transportation, employment, medical services, retail services, recreation, entertainment and much more. Housing is such a basic need that if a person does not have a safe and stable place to live, they are not going to be successful in any other area.

Question 5: A car used 1164 gallon of gas to drive ya of a mile. At this rate, how many miles can the car travel using 1
Sergeu [11.5K]

Answer:

Hello! Your answer is BELOW

Step-by-step explanation:

Car will cover 16 miles in 1 gallon of the gas.

We can solve this question by unitary method.

∵ A car used \frac{1}{64} gallons of gas to drive the distance =  \frac{1}{4} miles

∴ Car used 1 gallons to drive the distance = \frac{1}{4} \\\\\frac{1}{64}

= \frac{64}{1}  X    \frac{1}{4}

= \frac{64}{4}

= 16 miles

Therefore, car will cover 16 miles in 1 gallon of the gas.

Hope I helped! Hope you make an 100%.
