Look below. The answers are bolded!

Step-by-step explanation:

1. 10x + 23

5+6(2x+3)-2x

Distribute first!

5 + 12x + 18 -2x.

Now you can combine like terms.

23 + 10x

2. 18x + 6

3(4x+8) + 3(2x-6)

Distribute first!

12x + 24 + 6x - 18

Now you can combine like terms.

18x + 6

3. -2x + 8

(32-8x)

____ ___

Divide 32 and -8x by 4.

32/4 = 8

-8x/4 = -2x

-2x + 8

4. 4x + 3

24x+18

______

Divide 24x and 18 by 6

24x/6 = 4x

18/6 = 3

Which of the following is equivalent to x^-1/2 1) -1/2x 2) -√x 3) 1/√x 4) -1/2x

irina [24]

Answer:

Option (3) is correct.

Step-by-step explanation:

We need to find the expression that is equivalent to $x^{-1/2}$ .

The property is : $x^{-a}=\dfrac{1}{x^a}$

Here, a = 1/2

So,

$x^{-1/2}=\dfrac{1}{x^{1/2}}$

We know that, $x^{1/2}=\sqrt{x}$

$\dfrac{1}{x^{1/2}}=\dfrac{1}{\sqrt{x} }$

So, $x^{-1/2}$ is equivalent to $\dfrac{1}{\sqrt{x} }$

Hence, the correct option is (3).
