Answer:

D)  x² -x - 10  =0

Step-by-step explanation:

Given that

             \frac{2}{3x-6} - \frac{1}{3x+6} = \frac{1}{3}

L.C.M

         \frac{2(3x+6)-(3x-6)}{(3x+6)(3x-6)} = \frac{1}{3}

        \frac{(6x+12-3x+6)}{(3x+6)(3x-6)} = \frac{1}{3}

          \frac{(3x+18)}{((3x)^{2} )-(6)^{2} } = \frac{1}{3}

    ⇒ 3(3x+18) = 9 x^{2} - 36

   ⇒ 9 x + 54 = 9 x² - 36

  ⇒ 9 x² - 36 - 9x - 54 =0

⇒ 9 x²  - 9x - 90 =0

⇒ 9(x² -x - 10 ) =0

⇒ x² -x - 10  =0

Prove the identity 2csc2x=csc^2xtanz
Verizon [17]

Step-by-step explanation:

Consider the LHS, after the 5th step, consider the RHS

2 \csc(2x)  =  \csc {}^{2} (x)  \tan(x)

2 \frac{1}{ \sin(2x) }  =  \csc {}^{2} (x)  \tan(x)

2  \times \frac{1}{2 \sin(x)  \cos(x) }  =  \csc {}^{2} (x)  \tan(x)

\frac{1}{ \sin(x) \cos(x)  }  =   \csc {}^{2} (x)  \tan(x)

\csc(x)  \sec(x)  =  \csc {}^{2} (x)  \tan(x)

Consider the RHS

\csc(x)  \sec(x)  =( 1 +  \cot {}^{2} (x) ( \tan(x))

\csc(x)  \sec(x)  =  \tan(x)  +  \cot(x)

\csc(x)  \sec(x)  =  \frac{ \sin(x) }{ \cos(x) }  +  \frac{ \cos(x) }{ \sin(x) }

\csc(x)  \sec(x)  =  \frac{1}{ \sin(x) \cos(x)  }

\csc(x)  \sec(x)  =  \csc(x)  \sec(x)

djyliett [7]
Subtract $3 from $21 to get the cost of skating for three hours without the rental fee. 21-3=18. $18 was spent on skating for three hours so you'll divide 18 by 3 to get the hourly rate. 18/3=6.
