[tex]\frac{1}{x {}^{2} - 3 } = \frac{ \sqrt{3} }{x + \sqrt{3} } - \frac{2}{ \sqrt{3} - x } [/tex]
can someone please solve this?
Answers
Answer:
[tex]\boxed{\textsf{ The value of x is \textbf{ 8 + 6}$\sqrt{3 }$.}}[/tex]
Step-by-step explanation:
Here we are given a equation which we need today simplify and solve for x .The given equation to us is :-
[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } [/tex]
Let's simplify the equation :-
[tex]\sf\implies \dfrac{1}{x {}^{2} - 3 } = \dfrac{ \sqrt{3} }{x + \sqrt{3} } - \dfrac{2}{ \sqrt{3} - x } \\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}-\dfrac{2}{-(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3}{x+\sqrt3}+\dfrac{2}{x-\sqrt3}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3(x-\sqrt3)+2(x+\sqrt3)}{(x+\sqrt3)(x-\sqrt3)}\\\\\sf\implies \dfrac{1}{x^2-3}=\dfrac{\sqrt3x-3+2x+2\sqrt3}{x^2-3}\\\\\sf\implies 1=\sqrt3x-3+2x+2\sqrt3 \\\\\sf\implies \sqrt3x+2x = 4-2\sqrt3\\\\\sf\implies x(\sqrt3 +2)=4-2\sqrt3\\\\\sf\implies x =\dfrac{4-2\sqrt3}{\sqrt3+2}\\\\\sf\implies x =\dfrac{ (4-2\sqrt3)(\sqrt3-2)}{(\sqrt3+2)(\sqrt3-2)}\\\\\sf\implies x =\dfrac{-8-6\sqrt{3}}{3-4}\\\\\sf\implies \boxed{\pink{\sf x =8+6\sqrt3}}[/tex]

rectangle has dimensions 12 litre into 6 CM if you draw a square on the same perimeter what will be its area
Answers
Answer:
[tex]Area = 81cm^2[/tex]
Step-by-step explanation:
Given
[tex]Length = 12[/tex]
[tex]Width = 6cm[/tex]
Required
Determine the area of a square with the same perimeter
First, calculate the perimeter (P) of the rectangle.
[tex]P=2*(Length + Width)[/tex]
[tex]P=2*(12 + 6)[/tex]
[tex]P=2*18[/tex]
[tex]P=36[/tex]
The perimeter of a square is:
[tex]P = 4L[/tex]
Where L is the side length.
Substitute 36 for P
[tex]36 = 4L[/tex]
Make L the subject
[tex]L =\frac{36}{4}[/tex]
[tex]L =9[/tex]
The area of the square is:
[tex]Area = L^2[/tex]
[tex]Area = 9^2[/tex]
[tex]Area = 81cm^2[/tex]

8x – y = 42
-43 - 6 = y
Answers
Answer:
x = .875 y = -49
Step-by-step explanation:
(8x - y = 42)
(y = -43 - 6) or (y = -49)
Since we have our y value, we can plug it into our top equation:
8x -(-49) = 42
8x + 49 = 42
-42 -42
8x = 7
/8 /8
x = 0.875
To check the work:
8(0.875) - 49 = 42
7 - 49 = 42

Answer:
A) $287.60.
B) $323.55.
C) David would pay more for the laptop at the store.
Step-by-step explanation:
A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:
100 - 60 = 40
719 x 0.40 = X
287.6 = X
Therefore, in this case the sale price would be $ 287.6.
B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:
(719 x 0.5) x 0.9 = X
359.5 x 0.9 = X
323.55 = X
Thus, the sale price in the present case would be $ 323.55.

Answers
Answer:
the answer is 59 (I got it on khan academy)
Step-by-step explanation:
59 degrees is the measures of the minor arc YZ if diameter of a circle is XZ
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that diameter of a circle is XZ
We have to find the measure of arc YZ.
11w+5w+4=180
Add the like terms
16w+4=180
Subtract 4 from both sides
16w=176
Divide both sides by 16
w=176/16
w=11
Now plug in w value of yz
yz=5w+4
=5(11)+4
=55+4
=59 degrees
Hence, 59 degrees is the measures of the minor arc YZ.

Write an equation of the line through (-2, - 1) having slope
8/7?
Answers
Answer:
When slope and one point are known follow instructions on this page:
http://www.1728.org/distance.htm
Calculate "b" from this equation:
b = y -mx where "m" is the slope
We'll use the point given (-2, -1) for "x" and "y"
b = -1 -(8/7) * -2
b = -1 + 16/7
b = 9/7
then we enter "b" and the slope into this equation
y = 8/7x +9/7
y = 1.142857 x + 1.2857142857
