So you have to plug in the amount to the cost making you problem look like this:
0.85(30)+2.5(2)
25.5+5=30.5
        
             
        
        
        
So the formula for this is for every inch of width, you multiply by 2 to get the length. 
Here, I made a table for it. 
2×2=4
4×2=8
7×2=14
8×2=16 or 16÷2=8
 
        
        
        
Answer:
Hi there! 
The answer to this question is:
Standard: y= x- (cube root) z
the leading coefficient: 1
 
Step-by-step explanation:
when identifying a polynomial you always need to know the standard equation, and leading coefficient.
-you first need to know what "y" so you move y to the other side by adding it on both sides
-then you need to get y by itself and cube root it on both sides resulting in x^3 becoming x and z becoming (cube root) z
 
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
Recall that the area of a triangle is given by: 

In this case, the base is <em>x</em> and the height is <em>y</em>. Hence: 

We can write the following ratios: 

Solve for <em>x</em> and <em>y</em>: 

Substitute: 

And simplify. Hence: 

In conclusion, our answer is D.
