Solve for x. please i need know

Answers

Answer 1

Answer:

x = 18

Step-by-step explanation:

Vertically opposite angles are equal.

x + x + x + 90 = 144

3x + 90 = 144

Subtract 90 from both sides

3x = 144 - 90

3x = 54

Divide both sides by 3

x = 54/3

x = 18

Answers

Answer:

75 in^2

Step-by-step explanation:

Given data

From the figure

We can see a rectangle and a triangle

The area of the rectangle is

Area= L*W

Area= 13*5

Area= 65 in^2

Area of the triangle

Area= 1/2b*h

Area= 1/2*4*5

Area= 2*5

Area= 10 in^2

Hence the area of the composite figure is

Area= 65+10

Area= 75 in^2

10x-18=15x+48 solve for the x please.

Answers

Answer:

The total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

Step-by-step explanation:

Complete question

Tom started a stamp collection with 32 stamps. Each week he added 8 stamps to his collection.

Rhea started her stamp collection with 102 stamps. Each week she gave away 6 stamps.

Write an equation to represent the number of stamps in Tom’s collection based on the number of weeks he has been collecting stamps.

Solution

Let "X" be the number of weeks for which Tom collected the stamps

The number of stamps that Tom had at the time of starting the collection [tex]= 32[/tex]

It is given that he collects 8 stamps per week

So the total number of stamps that Tom collect at the end of X weeks is

[tex]32 + 8 * X[/tex]

If using the method of completing the square to solve the quadratic equation
x² + 2x + 16 = 0, which number would have to be added to "complete the
square"?

Answers

Answer:

x=-1+\sqrt{15}i,\:x=-1-\sqrt{15}i

Step-by-step explanation:

For the given quadratic equation,x² + 2x + 16 = 0 the value of x will be x=-1+√15i, and x-=-1-√15i you must add 1 in order to complete the square.

What is a quadratic equation?

Any equation with the formula [tex]\rm ax2 + bx + c = 0[/tex] where x is a variable and a, b, and c are any real values; a quadratic equation is one where a ≠ 0.

It is given that the equation is, x² + 2x + 16 = 0,

The value of x obtained after solving the given equation is x=-1+√15i and x-=-1-√15i.

In order to complete the square you have to take out the following operations,

x² + 2x + 16 = 0

Add and subtract by 1 as

x²+2x+16+1-1

x²+2x+1 +15

(x+1)²+(√15)²

Thus, you must add 1 in order to complete the square.

4^11

Step-by-step explanation:

[(4^3)(4^4)]÷(4^1+4^-4)

using laws of indices

(4^3)(4^4)=4^(3+4)

=4^7

(4^1 +4^-4)=4^(1-4)

=4^-3

4^7/4^-3,recalling about laws of indices if the exponentials are dividiy ,you subtract the powers give their base is equal

4^7/4^-3=4^(7-(-3)

=4^(7+3)

=4^11

It should be a topic that's appropriate for educational purposes and that would interest a broad audience. Consider choosing a topic on which people can take action. You may choose from these topics: 1) violence in video games or movies does or does not influence young people. 2) Using animals as test subjects for medications is ethical or unethical. 3) Argue what is the best way to reduce homelessness in the United States. 4) Green energy is or is not a realistic alternative to fossil fuels. 5) Choose a local issue such as funding cuts or increases for public services like libraries, parks, police, or fire service. 6) Choose a local issue such as homelessness, environmental problems ( waste, water shortages, etc. ) or lack of mental health services. Or, if a different topic comes to mind and meets the criteria, you may use it. Once you have chosen a topic, do a quick online search to see if there is enough information available about it. If the topic is so broad that you think you cannot do it justice in a single paper, try narrowing it. One way to narrow a topic is to ask yourself questions to which you would like to learn the answers. For example, suppose the broad topic is this: Alternative medicines - helpful, unhelpful, or harmful? You might write down questions that make you curious, for example: 1) What types of alternatives medicines exist? 2) What ailments are alternative medicines claimed to be effective for? 3) What studies have been done about alternative medicines? 4) What results have doctors and patients reported? Such questions can guide your research. 1) Write your topic. 2) Write two or more questions that you would like answered about your topic. 3) If you wish to narrow your topic, write the narrow version here. 4) Phrase your topic as a research question that your project will answer.

Nitrogen is used by plants for leaf growth and green color.
