Given:
The equation is:

To find:
The value of n in terms of x.
Solution:
We have,

It can be written as

![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
On comparing the exponents, we get

Add 1 on both sides.


Divide both sides by 2.

Therefore, the value of n is terms of x is
.
Answer:
-1/2
Step-by-step explanation:
The slope of a perpendicular line is opposite reciprocal. So the opposite of 2 is -2, and the reciprocal of 2 is 1/2.
Answer:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
Step-by-step explanation:
Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.
Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.
All they give us is that Elena has less than $20 in her bank account.
So your answer may look like this:
-$5.50>x>$20
Elena has more than -$5.50 but less than $20.
There are 144 square inches in a square foot.
<u><em>Explanation</em></u>
A common size for floor tiles is 1 square foot in area.
We know that, <u> 1 foot = 12 inches. </u>
So, 1 square foot = (1 foot × 1 foot) = (12 inches × 12 inches ) = 144 square inches.
So, there are 144 square inches in a square foot.
The measure of an interior angle of a regular nonagon is 140 o.
