using
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>so
w^3 + 125z^3
= w^3 +(5z)^3
= (w + 5z)(w^2 - 5wz + 25z^2)
hope it helps
        
             
        
        
        
Answer:
the first step is to subtract the 2W from each sides of the equal sides
Step-by-step explanation:
P=2L+2W
the first step is to subtract the 2W from each sides of the equal sides
P-2W=2L+2W-2W
P-2W=2L
 
        
             
        
        
        
Answer:  is an asymptote
 is an asymptote
Step-by-step explanation:
Apply a table, and plug in values of x into the equation.  For example f(2)= . That's one of the points on the graph that we just found (2,6)

3 hours
On the way there, 1.5x12 = 18
On the way back, 1.5x10 = 15
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Assuming one root of a polynomial function is 

Then the other root is 

The reason is that , complex roots of polynomial functions occur in pairs.
One complex root is the conjugate of the other.
This means that, if 

is a root, then 

is also a root.
