Answer:
-4 - 17x
Step-by-step explanation:
Anything enclosed in parentheses must be done first if possible.  (3x + 2) is inside two sets of parentheses, but nothing can be done with 3x + 2.  
Multiplication must be done next.  [6(3x+2)-x] becomes 18x + 12 - x, or
17x + 12.
Now we have 4 - 17x - 12 + 4.  Combining like terms through addition and subtraction, we get 4 - 12 + 4 - 17x, or -4 - 17x.

The value of the factorial is 5!4!/7!2! = 2/7
<h3>What is factorial?</h3>
The product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. 
Given:
5!4!/7!2!
= 5!* 4*3*2!/7*6*5!*2!
=4*3/7*6
=12/42
=4/14
=2/7
Hence, 5!4!/7!2! = 2/7.
