7 × x - 7 × 20 
You could rewrite it this way, 7 x (x-20), but the answer above is better 'cause it takes away the grouping symbols
 
        
             
        
        
        
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width =  
 
Ratio = length/width
 
 
Simplifying the equation by applying the law of indices (division), we have;
 
 
 
 
Hence, rearranging the above values;

<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is 

From the question, the center of the circle is located at (-6,2) and the radius is 

We substitute the center and radius to get:

Simplify to obtain:
