20.5 is the IQR of the given set of numbers.
As an example, 534 can also can also be written as:
- five hundred thirty four
-500+30+4
(if you're still confused, feel free to comment and I will help you with the others)
To find the magnitude of a vector, take the components, square them, then add them, then take the square root. This is very similar to the Pythagorean Theorem.
For your particular problem, I’ve included a picture showing how that specific calculation is done. :)
Answer:
<u>(x + 3)(x - 7)</u>
<u>(x + 1)(x - 2)</u>
Step-by-step explanation:
The general form of factored equations :
<u>y = (x + a)(x + b)</u> [it can be ±, so don't worry about that part]
===============================================================
Hence, the expressions which are in factored form :
⇒ <u>(x + 3)(x - 7)</u>
⇒ <u>(x + 1)(x - 2)</u>
