What is the value of x3 + x2 + when x=3​

Answer:

Step 2: 20x = 80 + 10x

Step-by-step explanation:

Step 1: 20x - 10 = 80 + 10x

Add 10 to each side

20x - 10+10 = 80+10 + 10x

20x  = 90 + 10x

Step 2: 20x = 80 + 10x   This has the first error

Step 3: 10x = 80

Step 4: x= 8

Answer:

the temperature at noon was 22    can i get brainliest please? :)

Step-by-step explanation:

-5 + 27 = 22

The temperature at noon after a rise of 27°C will be 22°C.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem accurately and completely.

At sunrise, the temperature outside was 5°C below zero By noon the temperature rose to 27°C. Then the temperature at noon is given as,

⇒ 27°C + (-5°C)

⇒ 27°C - 5°C

⇒ 22° C

The temperature at noon after a rise of 27°C will be 22°C.

Answer:

.41

Step-by-step explanation:

1ft = 0.000189394mi

0.000189394 x 6mi =0.00113636mi

1 year = 365 days

365 x 0.00113636 =0.41477286

The given speed in miles per year should be 0.41477286.

Given that,

Based on the above information, we know that

1 feet = 0.000189394miles

Now there are 6 feet.

So, for 6 feet, the miles should be  

= 0.000189394 × 6mi

= 0.00113636mi

Now for per year, it should be  

= 365 × 0.00113636

= 0.41477286

Therefore we can conclude that the given speed in miles per year should be 0.41477286.

Answer:

-3

Step-by-step explanation:

Step 1: Write equation

-7.6(x - 1) = 7.3 - 7.4x

Step 2: Solve for x

Distribute -7.6: -7.6x + 7.6 = 7.3 - 7.4x

Add 7.6x on both sides: 7.6 = 7.3 + 0.2x

Subtract 7.3 on both sides: 0.3 = 0.2x

Divide both sides by 0.2: x = 1.5

Step 3: Find -2x

-2(1.5) = -3

Answer:

3

Step-by-step explanation:

-7.6x+7.6=7.3-7.4x

-7.6x+7.4x=7.3-7.6

-0.2x=-0.3

X=-0.3/-0.2

X=3/2

2x. means multiply the ans you get for x by 2

Answer:

1) ( 6+[tex]\sqrt{6}[/tex] ) / 2                 2) 2 [tex]\sqrt{3}[/tex] - 3

Step-by-step explanation:

I got the same thing as the other person, but typing it out would take forever just to give you the same result.

You do use a technique called rationalizing a denominator to eliminate the radical. The point of rationalizing a denominator is to make it easier to understand what the quantity really is by removing radicals from the denominators.

1) ( 6+[tex]\sqrt{6}[/tex] ) / 2

2) I got the same answer but I put in 1 more step. It looks like the person caught it though.

From the -3 + [tex]\sqrt{12}[/tex]    

-3 + [tex]\sqrt{4} \sqrt{3}[/tex]

-3 + 2 [tex]\sqrt{3}[/tex]     Rearrange

2 [tex]\sqrt{3}[/tex] - 3

Answer:

3.75, Terminating

Step-by-step explanation:

To answer this, we simply have to find what 3/4 is as a decimal. So, we know that in order to make 4/4, or 1, we need 4 parts. Let's say that 4/4 would equal 100, so we need to divide 100 into 4 parts:

100 / 4 = 25

Now, to find what 3/4 is, all we have to do is multiply 25 by 3:

25 * 3 = 75

And that is our decimal form, we just need to add the 3:

3.75, and since .75 doesn't keep on repeating, it just stops at .75, this is a terminating decimal

Hope this helps! :)
