Answer:

$a = \dfrac{46}{17}$

$b = 0$

Step-by-step explanation:

$\dfrac{2\sqrt{5} + \sqrt{3}}{2\sqrt{5} - \sqrt{3}} + \dfrac{2\sqrt{5} - \sqrt{3}}{2\sqrt{5} + \sqrt{3}} =$

$= \dfrac{2\sqrt{5} + \sqrt{3}}{2\sqrt{5} - \sqrt{3}} \times \dfrac{2\sqrt{5} + \sqrt{3}}{2\sqrt{5} + \sqrt{3}} + \dfrac{2\sqrt{5} - \sqrt{3}}{2\sqrt{5} + \sqrt{3}} \times \dfrac{2\sqrt{5} - \sqrt{3}}{2\sqrt{5} - \sqrt{3}}$

$= \dfrac{23 + 4\sqrt{15}}{17} + \dfrac{23 - 4\sqrt{15}}{17}$

$= \dfrac{46}{17}$

$a = \dfrac{46}{17}$

$b = 0$

Solve for x. −6>−30−4x−6>−30-4x enter the inequality in the first box.

Bogdan [553]

If you would like to solve -6 > -30 - 4x for x, you can do this using the following steps:

-6 > -30 - 4x
4x > -30 + 6
4x > -24 /4
x > -24/4
x > -6

The correct result would be x > -6.
