Answer:
336 version
Step-by-step explanation:
To determine the total possible number of combination we will use the product rule
Total numbers of exterior colour 7
Total number of interior colour 3
Total number of interior style 4
Total number of transmission option 2
Total number of engine option 2 therefore the total combination is
7*3 *4*2*2 = 336 possible combination
 
        
             
        
        
        
Answer:

Step-by-step explanation:
So we have the expression: 

And we wish to factor it. 
First, let's make a substitution. Let's let u be equal to x². Therefore, our expression is now: 

This is a technique called quadratic u-substitution. Now, we can factor in this form. 
We can use the numbers -3 and -2. So: 

For the first two terms, factor out a u. 
For the last two terms, factor out a -3. So: 

Grouping: 

Now, substitute back the x² for u: 

And this is the simplest form. 
And we're done!
 
        
             
        
        
        
Hey there!
Okay let's get cracking :D
The equation is....  (2x/3) - 6 = 9
2x/3 = 15
2x = 45
<u>x = 22.5</u><u />    <----- And that is your answer!
I hope it helped!
