<span>v(x)=(s/t)
= (3x - 6) / (-3x+6)
= [3(x-2)] / [-3(x-2)] --> 3 is factored out
= 1/-1 </span>---> common terms are cancelled out. 
= -1 ---> This is the
simplified formula.
To find the domain, we equate the denominator to 0.
-3x+6 = 0
3x = 6
x = 2
Domain: all values except 2.
w(x)=(t/s)(x)
= (-3x+6)x / (3x-6)
= [-3x(x-2)] / [3(x-2)] --> 3 is factored out
= -x --> The common terms are cancelled out. This is the simplified formula.
Solving for domain:
3x-6 = 0
3x = 6
x = 2
Domain: all values except 2.
 
        
             
        
        
        
if a=3,for example, and B=2, and we plug it in:
p=(3)(2)  which is p=6
q=(2)(3) which is also =6
the factor order wont change the product
 
        
             
        
        
        
8n + 5 = 139
You would re-Arrange it to make it 
8n = 139 + 5 
Then take minus five to make it look like
8n=134
Next step would be to divide 
Divide 8 on both sides which would leave you with 
N= 67 over 4 
you will have to convert it if you don’t want a fraction
        
             
        
        
        
K^2 +3k +5k + 15
k (k+3) +5 (k+3)
(k+5)(k+3)
So, the correct option is the last one.
