Answer 20 I just did that question
        
             
        
        
        
To factor first multily 100 and 1 and get 100
then find what 2 numbers multiply to get 100 and add to get 20
the numbers are 10 and 10
so 
split the center term up
100x^2+10x+10x+1
group
(100x^2+10x)+(10x+1)
undistribute
(10x)(10x+1)+(1)(10x+1)
undistribute/reverse distributive property
(10x+1)(10x+1)
(10x+1)^2
        
                    
             
        
        
        
Answer:
2x-3 = -11
Step-by-step explanation:
|2x-3| = 11
by definition of absolute numbers, 
2x-3 = 11 (given) 
or 
2x-3 = -11 (answer)
 
        
             
        
        
        
The constant of proportionality is 3/8
