What is square root of 22
zmey [24]

Final Answer: 4.69

Steps/Reasons/Explanation:

<u>Step 1</u>: You will need to find the perfect square root of a number that is less than 22. So 4^{2} is 16.

<u>Step 2</u>: Write down the square root of 16 = 4.

<u>Step 3</u>: Solve \frac{22 - 16}{4 * 2} which is 0.75.

<u>Step 4</u>: Add 4 + 0.75 = 4.75, so \sqrt{22} is approximately ≈4.7.

Solve the inequality below. Use the drop-down menus to describe the solution and its graph.
aniked [119]

Answer:

x < -4

Step-by-step explanation:

Hello!

I don't see the drop-down menus, but I will try to help as best as I can...

Like any other equation, you are trying to get x by itself.

Our first step will be to subtract 13 from both sides.

-7x + 13 > 41

-7x > 28

Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.

-7x/-7 > 28/-7

Doing the above equation will provide us with x all alone on one side:

x < -4

Hope I helped!

Which shows the expressions rewritten with the least common denominator? 5x+3/3x and 7x/2x^2
andrey2020 [161]

Answer:

\frac{10x^2+6x}{6x^2} and \frac{21x}{6x^2}.

Step-by-step explanation:

The given expression is:

\frac{5x+3}{3x} and \frac{7x}{3x^2}.

The least common denominator is: 6x^2.

We collect  LCM for the denominator to obtain;

\frac{2x(5x+3)}{6x^2} and \frac{3(7x)}{6x^2}.

We multiply out the parenthesis to obtain;

\frac{10x^2+6x}{6x^2} and \frac{21x}{6x^2}.

Therefore the correct answer is B or the second option.
