X would be 10, and 2 because:
(10-10) = 0 and (2-2) = 0
The extraneous solution is correct because the equation does not hold true when x is 2 and only hold trues when it is 10.
Edit: the extraneous solution is 2 is because it doesn't hold true to the equation.

Solve the quadratic equation by completing the square.
x^2 - 18x + 68 = 0
First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation. Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
Answers
Answer:
x = x = 9 ±[tex]\sqrt{13}[/tex] or x ≈ 12.61 or x ≈ 5.39
Step-by-step explanation:
x² - 18x + 68 Solve by completing the square.
x² - 18x = - 68
Now complete the square and add that number to both sides of the equation.
1/2 (of the coefficient of the x term)² = (1/2 · -18)² = 81 .
x² - 18x + 81 = -68 + 81
(x - 9) (x - 9) = 13 Now find the square root of both sides
[tex]\sqrt{(x - 9)(x - 9)}[/tex] =[tex]\sqrt{13}[/tex] Solve
x - 9 = ±[tex]\sqrt{13}[/tex] Solve for x
x = 9 ±[tex]\sqrt{13}[/tex]
x = 9 + [tex]\sqrt{13}[/tex] or x = 9 - [tex]\sqrt{13}[/tex]
x ≈ 12.61 or x ≈ x 5.39

There are 6 yellow, 4 orange, 2 green, and five blue plastic building blocks all the same
size in a bag. What is the probability of selecting an orange, putting it back, then
а
selecting a block that is not orange.
Answers
We want to get the probability of selecting an orange, putting it back, then selecting a block that is not orange.
We will see that the probability is P = 0.1799
In the bag we have:
6 yellow blocks4 orange blocks2 green blocks5 blue blocks.For a total of 6 + 4 + 2 + 5 = 17 blocks.
First we want to find the probability of getting an orange block, as all the blocks have the same probability of being randomly drawn, the probability of randomly drawing an orange block is equal to the quotient between the number of orange blocks and the total number of blocks.
We get:
p = 4/17
Now we put the orange block back and we want to take a block that is not orange, the probability is computed in the same way:
q = (6 + 2 + 5)/17 = 13/17
The joint probability (this is, the probability of these two events happening together) is just the product of the individual probabilities.
We get:
P = p*q = (4/17)*(13/17) = 52/289 = 0.1799

Use the Distributive Property:

Move all the constants to the left side:
3.6w-1.6w=24
2w=24
Divide both sides by 1.8 to isolate w:

Answer:
W=12
Step-by-step explanation:
3.6w=2(0.8w+12)
3.6w=1.6w+24
Subtract 1.6w from both sides
3.6w-1.6w=1.6w+24-1.6w
Simplify
2w=24
Divide both sides by 2
2w/2=24/2

x=[tex]\sqrt{2}[/tex]/4 and x=-[tex]\sqrt{2}[/tex]/4
Step-by-step explanation:
One method of solving is using the Quadratic Formula: -b ±[tex]\sqrt{b^{2}-4ac }[/tex]/2a, with a=8, b=0, and c=-1.
After plugging these values in you get -0±[tex]\sqrt{0^2-(4*8*-1)}[/tex]/2*8
After simplifying you get ±[tex]\sqrt{32}[/tex]/16
Because 32 is 2^5, you can simplify it to 4[tex]\sqrt{2}[/tex], which makes the equation ±4[tex]\sqrt{2}[/tex]/16, or ±[tex]\sqrt{2}[/tex]/4.

Prompt - Select an image of an art work from smarthistory by looking at the "Histories of Art" tab.
Objective - This is an exercise to get comfortable with applying the language of art as well as the steps of the Art Analysis ChartActions (summarized below).
You must include in this exercise four short, clearly separated paragraphs (2-3 sentences) consisting of the concerns printed in bold:
1. description of the chosen image (include the image information: title, artist's name, year, medium, etc.) and say what you see.
2. analysis of what you see by saying what each element is achieving (e.g. "converging lines are used to draw our attention to the focal point.")
3. interpretation of the image by saying what the work is about and what it means.
4. evaluation of the image by talking about where you think the "value" lies in your chosen image, and explain why. The term value here is not in the context of light or dark as in formal attributes. It refers to what is significant in the work of art you are analyzing, and how successful or unsuccessful it has been executed. Evaluation here is an exercise in reasoning/arguing based on your previous three paragraphs.

Does 3(2k-5)=6(k-4)+9 have no solution of many solutions
Answers
Answer:
infinite (many)
Step-by-step explanation:
3(2k-5)=6(k-4)+9
6k-15=6k-15
since they are the same on both sides of the equal side any solution for x would work.
The equation 3(2k - 5) = 6(k - 4) + 9 has many solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
3(2k - 5) = 6(k - 4) + 9
6k - 15 = 6k - 24 + 9
6k - 15 = 6k - 15
Both sides of the equation are the same.
This means,
The equation has many solutions.
Thus,
The expression has many solutions.
