Answer:

-2c

Step-by-step explanation:

The given expression is

\frac{1}{8}(-8c+16)-\frac{1}{3}(6+3c)

We need to find the simplified form of the given expression.

Using distributive property we get

\frac{1}{8}(-8c)+\frac{1}{8}(16)-\frac{1}{3}(6)-\frac{1}{3}(3c)

-c+2-2-c

On combining like terms we get

(-c-c)+(2-2)

-2c+0

-2c

Therefore, the simplified form of the given expression is -2c.

\frac{1}{8}(-8c+16) - \frac{1}{3}(6+3c)

This may look scary, but all you have to do is distribute, first:
(-c+2)-(2+c)

Now it's much easier (remember to distribute the negative):
-c+2-2-c = -2c

So, the entire thing simplifies to -2c. NEAT!

Select all irrational numbers.
Maurinko [17]

Answer:

OPTION A

OPTION B

OPTION C

Step-by-step explanation:

Irrational numbers are the subset of real numbers. Their decimal representation neither form a pattern nor terminate.

OPTION A: $ \sqrt{\frac{1}{2}} $

This is equal to $ \frac{1}{\sqrt{2}} $.

$ \sqrt{2} = 1.414... $ is non-terminating. So, it is an irrational number. Hence, the reciprocal of an irrational number would also be irrational. So, OPTION A is irrational.

OPTION B: $ \sqrt{\frac{1}{8}} $

This is equal to $ \frac{1}{2\sqrt{2}} $. Using the same logic as Option A, we regard OPTION B to be irrational as well.

OPTION C: $ \sqrt{\frac{1}{10}} $

This is equal to $ \frac{1}{\sqrt{5}\sqrt{2}} $.

Both $ \sqrt{5} $ and $ \sqrt{2} $ are irrational. So, the product and the reciprocal of the product is irrational as well. So, OPTION C is an irrational number.

OPTION D: $ \sqrt{\frac{1}{16}} $

16 is a perfect square and is a rational number. $ \frac{1}{\sqrt{16}} $ = $ \frac{1}{4} $. This is equal to 0.25, a terminating decimal. So, OPTION D is a rational number.

OPTION E: $ \sqrt{\frac{1}{4}} $

4 is a perfect square as well. $ \frac{1}{\sqrt{4}} = \frac{1}{2} = 0.5 $, a terminating decimal. So, OPTION E is a rational number.
