Answer:

Step-by-step explanation:
We can rewrite the question as (x-5)*(x-5).
Using the FOIL Method (First, Outside, Inside, Last):

This simplifies to 
 
        
                    
             
        
        
        
The answer is 128......
if you expand them
-27 x -1024 x 216 divide by 216 x216
= -27 x -1024 divided by 216
-1024 x -1 divided by 8
= 1024 / 8
=128

Answer:
The slope is -1/2 and the y intercept is 1/4
Step-by-step explanation:
y = -1/2x + 1/4
This equation is in slope intercept form 
y = mx+b where m is the slope and the y intercept is b
The slope is -1/2 and the y intercept is 1/4
 
        
             
        
        
        
Answer:
Option D is correct 
Step-by-step explanation:
Using the given diagram, we want to know the equation that is true 
Option A is wrong as both are on a straight line and in fact should add up to equal 180 and not be equal to each other 
Option B is not correct as both are supplementary and does not equal each other 
Option C is not correct, both are corresponding to each other and should not add up to 90
Option D is correct 
Both angles are supplementary as they are exterior angles that add up to 180
