Which expression is equal to 5/(sqrt)11?
horrorfan [7]

Answer:

Option A is correct

the expression is equal to \frac{5}{ \sqrt{11}} is \frac{5\sqrt{11}} {11}

Explanation:

Given expression is, \frac{5}{ \sqrt{11}}

Multiply and divide by the denominator by \sqrt{11} in the given expression, we have,

\frac{5}{\sqrt{11}} \times \frac{\sqrt{11}} { \sqrt{11}}

or

\frac{5 \cdot \sqrt{11}} {\sqrt{11} \cdot \sqrt{11}}

use : \sqrt{a}\cdot\sqrt{a}=(\sqrt{a} )^2 = a

then;

\frac{5\sqrt{11}} { (\sqrt{11})^2} =\frac{5\sqrt{11}} {11}

Therefore, the expression is equal to \frac{5}{ \sqrt{11}} is, \frac{5\sqrt{11}} {11}

What are two different way of factoring -3x-9? Select all that apply
Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

-3x - 9

Required

Factorize

The options are not given; So, I'll answer on a general term

-3x - 9

Express -9 as -3 * 3

-3x - 9 = -3x - 3 * 3

Then factorize 3 out of the expression as:

-3x - 9 = 3(-x - 3)

Another way is to factor -3 out of the expression as:

-3x - 9 = -3x - 3 * 3

-3x - 9 = -3(x + 3)
