Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:
c(p) = 0.42p
Where: c(p) = total cost of sugar bought
p = pounds of sugar
c(p) is a function of p, because c(p) depends on p.
        
                    
             
        
        
        
Answer:
1. x = 10
2. x = 4
Step-by-step explanation:
I use the angle ABC method: 
AB² + AC² = BC²
6² + 8² = x²
x = 10 
AB² + AC² = BC²
3² + x² = 5²
x = 4

It should be noted that Polygon 3 and polygon 4 are similar to polygon 1. 
<h3>
What exactly is polygon?</h3>
In geometry, it should be noted that a polygon is a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.
In this case, the bounded plane region, the bounding circuit, may be called a polygon. Also, a similarity transformation is the conformal mapping whose transformation matrix are identical.
In this case, it should be noted that Polygon 3 and polygon 4 are similar to polygon 1.

It depends on the line or parabola that you are talking about, more information would be needed to answer this correctly.
