Step-by-step explanation:
A) can be simplified into -> (x ([tex]\sqrt{3}[/tex] * x - 3*[tex]\sqrt{3y}[/tex])/3)
B) Can be simplified into ([tex]\sqrt{2x}[/tex]/2) + ([tex]\sqrt{2z}[/tex]/2)
D) Can be simplified into 5*[tex]\sqrt{5x}[/tex] - x^2
Therefore, C is the correct answer because it cannot be simplified any further!

What is x and the unknown angle? May I also get a brief explanation of how to do it?
Answers
Answer:
149+(13x+5)=180
154+13x=180
13x=26
x=2
Answer:
see explanation
Step-by-step explanation:
The 2 angles are adjacent on a straight line and sum to 180° , then
149 + 13x + 5 = 180 , that is
154 + 13x = 180 ( subtract 154 from both sides )
13x = 26 ( divide both sides by 13 )
x = 2
Then
unknown angle = 13x + 5 = 13(2) + 5 = 26 + 5 = 31°

A rectangles length is 6 units greater than its width. Write an equation expressing the rectangles area, A, as a function of W
Answers
Answer:
A = W² + 6W
Step-by-step explanation:
The width is W.
The length is 6 units greater than the width, so the length is W + 6.
The area is the product of the length and width.
A = (W + 6)W
A = W² + 6W
Solve the following expression when

Step-by-step explanation:
(4k + 2) ÷ 10
(4(12) + 2) ÷ 10
(48 + 2) ÷ 10
(50) ÷ 10
= 5
Hope this helps!! <3
The solution to the expression (4k + 2 ) ÷ 10 when k = 12 is 5
From the given expression, we are to solve for (4k + 2) ÷ 10
When
k = 12What we are going to do is that we will replace k with 12 wherever we see (k) in the expression given
∴
= (4k + 2 ) ÷ 10
= (4(12) + 2 ) ÷ 10
= (48 + 2) ÷ 10
= (50) ÷ 10
= 5

James is selling a bike on an internet auction website. he pays £1.45 insertion fee, £2.85 for an enhanced advert and a selling fee of £1.95 when the bike is sold. what are his total selling fees to the nearest pound (£)
Answers
Hello :D
£1.45 + £2.85 = £4.30
£4.30 + £1.95 = £6.25
£6.25 to the nearest pound = £6.00
Answer: Selling fees = £6 (rounded to the nearest pound)
Step-by-step explanation:
Given information
Insertion fee = £1.45
Enhanced advert = £2.85
Selling fee = £1.95
Given expression deducted from the given information
Total = insertion + enhanced advert + selling
Substitute values into the expression
Total = (1.45) + (2.85) + (1.95)
Simplify by addition
Total = 4.3 + (1.95)
Total = 6.25

write and solve an equation to find the value of X. please explain in details and show your work!

The answer is x=34 degrees.
The answer you are looking for is x=34.
Solution/Explanation:
First things first, we need to understand that the sum of the angles of a triangle is 180°. We can apply this fact for the problem.
So, that means that the sum of all of the angles of this triangle is 180°.
So, therefore, we can formulate an equation:
2x+20+2x-10+x=180.
So, we now have our expression.
Now, all we need to do is simplify it.
Combining similar-like terms,
2x+2x+x+20-10=180.
Simplifying it now,
5x+10=180.
Subtracting 10 from both sides of the equation,
5x+10-10=180-10.
5x=170.
Finally, dividing both sides by 5,
5x/5=170/5.
x=34.
So, therefore the final answer is x=34.
I hope that this has helped you. Enjoy your day, and take care!
