Step-by-step explanation:




<u>Answer: </u>
Simplified form of given expression (2x – 9 )( x + 6 ) is 
<u> Solution:
</u>
We need to simplify following expression.
(2x – 9) ( x + 6)
For sake of simplicity lets first assume 2x – 9 = A
So expression becomes A(x+6)
= Ax + A6
Now replace A by 2x – 9
= (2x – 9 ) x + (2x – 9 ) 6

On simplification, we get

Hence simplified form of given expression (2x – 9 )( x + 6 ) is 
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
