Answer 1
5x+3x=8x
7x^2-5x^2=2x^2
2xy+4xy=6xy
8y-3y=5y
Answer 2

The solutions to the given expressions are given below:-

1. 5x +3x            ⇒   8x

2. 7x²- 5x²         ⇒   2x^2

3. 2xy +4xy       ⇒   6xy

4. 8y - 3y           ⇒   5y

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expressions will be solved as:-

1. 5x +3x

The sum of 5x and 3x is equal to 8x.

5x +3x = 8x

2.. 7x²- 5x²

The substraction of 7x² and 5x² is equal to 2x².  

7x²- 5x²  = 2x²

3. 2xy +4xy

The sum of 2xy and 4xy is equal to 6xy.

2xy +4xy = 6xy

4. 8y - 3y

The subtraction of 8y and 3y is equal to 5y.

8y - 3y = 5y

HELP PLESSE ITS MULTIPLE CHOICE

Answers

Answer:

Letter A

Step-by-step explanation:

First of all, we have to solve all the equations

First one is (4*1)-6

We have to use PEMDAS

which stands for

Parenthesis

Exponents

Multiplication

Divison

Addition

Subtraction

In (4*1)-6  

You have to do 4*1 first ~ which equals 4

the next step would be 4-6  ~  which equals -2

The next equation would be (1*4)-6

First do 1*4  ~ which is 4

Next 4-6  ~ which again equals -2

Next equation is (1*6)-(4-6)

Parenthesis first, 1*6=6

4-6=-2

6-(-2)

which equals 8

Our next equation is 6-(1*4)

1*4=4

6-4~ which equals 2

Our last equation is 4*(1-6)

Parenthesis comes first, so it would be 1-6 first

which equals -5

4*(-5) would be our final step  ~  which equals -20

All of our answers would be

-2 - from the top equation

-2 - from letter A

8 - from letter B

2 - from letter C

-20 - from letter D

which means Letter A is the answer.

Hope this is helpful.

When the light's energy is _______, this causes the highway to gain energy and warm up. Read the passage below and answer the question.Once people had developed food production to the point of being able to store surpluses, the human population began to grow more rapidly; from 8000 to 3000 BCE it increased from 6 to 50 million. Some people began to live in cities of 10,000 to 50,000 inhabitants. In cities, people created a whole new range of ideas and structures that came to be called civilization (from the Latin civitas, for city) by Western historians. Among the characteristics of civilization usually cited are: storage of food, development of a priestly caste, central authority, nonagricultural specialists, social stratification, increased trade, development of writing, tribute forcibly collected from outlying farmers, development of soldiers and standing armies, monumental public works, and increased gender inequality.From: Cynthia Stokes Brown, Big History from the Big Bang to the Present (2012).According to the passage, what best describes the changes that occurred after the development of food production?Choose 1 answer:(Choice A)AGovernments became increasingly decentralized, ensuring more equality and freedom across groups(Choice B)BCivilizations emerged, which introduced more regimented social structures, which decreased social equality and limited peoples freedom(Choice C)CCivilizations emerged, which introduced more regimented social structures, ensuring more equality and freedom across groups(Choice D)DThe loose social structure that existed before the advent of food production was maintained Which of the following would increase as you move from the crust to the inner core?
