Answer:

5 - 2 \sqrt{6}

Step-by-step explanation:

Perhaps you are interested in rationalising the denominator of the given problem. Let's do it.

\frac{ \sqrt{3} -  \sqrt{2}  }{ \sqrt{3} +  \sqrt{2}  }  \\  \\ multiplying \: numerator \: and \: denominator \:  \\ by \: (\sqrt{3} -  \sqrt{2}) \\  \\  \frac{( \sqrt{3} -  \sqrt{2} ) }{ (\sqrt{3} +  \sqrt{2}  )}  \times  \frac{ (\sqrt{3} -  \sqrt{2}  )}{ (\sqrt{3}  -   \sqrt{2}  )}  \\  \\  =   \frac{{( \sqrt{3}  -  \sqrt{2} )}^{2} }{ { (\sqrt{3} })^{2}  -  {(  \sqrt{2} })^{2} }  \\  \\  =  \frac{ { (\sqrt{3} )}^{2} +   { (\sqrt{2} )}^{2}   - 2 \sqrt{3 \times 2}  }{3 - 2}  \\  \\  =  \frac{3 + 2 - 2 \sqrt{6} }{1}  \\  \\  = 5 - 2 \sqrt{6}

What is the value of x? There is isosceles triangle. The measure of angle which is between two congruent sides is (6x+10⁰). The
max2010maxim [7]
<h3><u>Answer</u><u>:</u><u>-</u></h3>

x=17

<h3><u>step-by</u><u>-</u><u>step</u><u> </u><u>Explanation</u><u>:</u><u>-</u></h3>

{\boxed{\quad\:\mapsto\rm Firstly\:Let's\:understand\:the\:concept:-}}

<h3 />

This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Given angles

  • (6x+10°)
  • (x+17°)
  • (4x-34)°

According to sum theory

{\boxed{\sf The \:sum\:of\:angles=180°}}

  • Substitute the values

\qquad \quad{:}\longmapsto\tt (6x+10)+(x+17)+(4x-34)=180

  • Remove brackets

\qquad \quad{:}\longmapsto\tt 6x+10+x+17+4x-34=180

  • Together like polynomials and constants

\qquad \quad{:}\longmapsto\tt 6x+x+4x+10+17-34=180

\qquad \quad{:}\longmapsto\tt 11x-7=180

  • Interchange sides

\qquad \quad{:}\longmapsto\tt 11x=180+7

\qquad \quad{:}\longmapsto\tt 11x=187

\qquad \quad{:}\longmapsto\tt x=\cancel{\dfrac{187}{11}}

  • Simplify

\qquad \quad{:}\longmapsto\tt x=17

\therefore\sf The \:value\:of\:x\;is\:17.

Gas price dropped to 2.84 today yesterday’s price was 2.90 find the percentage decrease
IRISSAK [1]
Well, yesterday was 2.90 and today is 2.84, it dropped 6 pennies or $0.06.

now, if we take 2.90 to be the 100%, how much is 0.06 off of it in percentage?

\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;2.90&100\\&#10;0.06&p&#10;\end{array}\implies \cfrac{2.90}{0.06}=\cfrac{100}{p}\implies p=\cfrac{0.06\cdot 100}{2.90}

6 - 4x = -2x +2

6 = 2x +2

4 = 2x
