Which is the first step in simplifying the expression?

Elenna [48]

$\dfrac{3}{2 + \sqrt{2} }$

To rationalise the denominator, this is a standard step:
$= \dfrac{3}{2 + \sqrt{2} } \times \dfrac{2 - \sqrt{2}}{2 - \sqrt{2}}$

Answer: Option A

---------------------------------------------------------------------------------------------------

Let me continue to complete the question, though it is not ask for

$= \dfrac{3(2 - \sqrt{2})}{(2 + \sqrt{2)}(2 - \sqrt{2}) }$

$= \dfrac{3(2 - \sqrt{2})}{4 - 2 }$

$= \dfrac{6 - 2\sqrt{2}}{2 }$

Which of the following is a solution of 12 x - 7 > 6? -1 0 1 2

Mkey [24]

Answer:

The answer to your question is "2"

Step-by-step explanation:

Data

12x - 7 > 6

Process

1.- Add +7 in both sides of the inequality

12x - 7 + 7 > 6 + 7

2.- Simplify

12x > 13

3.- Divide by 12 both sides

12x/12 > 13/12

x > 13/12 or x > 1.08

4.- Conclusion

All the numbers higher than 1.08 are solutions of this inequality

Then, from the choices, the only possible solution is 2.
