Answer:
it look like its 4 and the 4 over 4/5 I think
 
        
                    
             
        
        
        
F(x) = 2x and G(x) = x^2 + 2
(G - F)(x) just means we subtract the functions from each other.
x^2 + 2 - 2x
Let's rearrange the expression
x^2 - 2x + 2
 
        
                    
             
        
        
        
Answer:
1 + 1 - 0 = 1
When you add 1 + 1, you receive 2. Then when you subtract 1, you are left with 1. 
 
        
                    
             
        
        
        
X=-8 
A negative plus a positive, if ghe negative is bigger it stays negative. -8 is bigger than 5 and 8 - 5 is 3 add the negative and you get -3
        
             
        
        
        
Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
