Here is the answer.
You just have to remember the given formula.
Distribute 1/2 to <span>(n – 4):
</span>


<span>
Subtract (2n + 3):
</span>

<span>
Your equation should now look like this:
</span>

<span>
Combine like terms on both sides:
</span>



<span>
Subtract 1/2n from both sides:
</span>

<span>
Divide both sides by -5/2 to get n by itself:
</span>

<span>
The value of n is
2.</span>
Answer:
<u><em>9 (3x+2)</em></u>
Step-by-step explanation:
<u>27x + 18 = 9 (3x+2)</u>

Find the area of the rectangle. You can find the area of a rectangle with the following formula:

w = width, and l = length.
Plug in your width and length:

The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:

The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
