Answer:
Min
Step-by-step explanation:
To check if it has a max or min, you must reference the a value. The a value in this case is 2, and that is positive. Positive parabolas point up, so they can only have a minimum point.
 
        
                    
             
        
        
        
Answer:
21
Step-by-step explanation:
The question is based in pigeonhole principle that says If n or  more  pigeons  are  distributed  among k >0 pigeonholes,then at least one pigeonhole contains at least  pigeons.
 pigeons.
8 + 6 + 9−3 + 1 = 21
 
        
             
        
        
        
Answer:
Plants are restrictive to flow of eroding agents, bind soil in their roots. 
Step-by-step explanation:
Soil Erosion is the wearing away of the topmost fertile layer of soil. Topsoil gets eroded mainly due to wind, water agents.
Plants help to prevent soil from erosion in following ways :
- Plants act as restriction to the speed of air & water, which are the main soil erosion agents. It also lets rain water get soaked into the ground water. 
- Plants roots also bind the soil tightly, & make soil stronger to be eroded by erosive agents - water, air. Eg : Shrubs , trees, grass & ground are important soil erosion preventive plants, because of their extensive root systems. 
 
        
             
        
        
        
Answer: EHB
or you could use angle BHE
or angle H, but I would try to use EHB 
 
        
             
        
        
        
This is same as (4x-6)(2x), so you can distribute 2x into 4x-6 and you would get
(2x)4x - (2x)6 = 8x² - 12x
Final answer: 8x² - 12x
Hope this helps.
