Answer:
The sensitive period for language is from 7 months in utero up to 5.5 to 6 years of age. There are several aspects of language from spoken language, to written language and reading. ... The sensitive period for learning to speak is from is from 7 months to 2.5-3 years of age.
Step-by-step explanation:
 
        
             
        
        
        
Pairs, in this case, relates to a group of 2 or more. We have 6 friends. Let's call them A,B,C,D,E,F. This will allow us to make a [some sort of] combination tree:
1. ABC against DEF
2. ABD against CEF
3. ABE against CDF
4. ABF against CDE
5. ACD against BFE
6. ACE against BDF
7. ACF against BDE
8. ADE against BCF
9. ADF against BCE
10. AEF against BCD
I believe there are 12 combinations... I just can't think of the last 2 though.
 
        
             
        
        
        
1) No; you are incorrect.  "0" is NOT a solution.
Plug in "0" for "x" ;
8*0² + 23 =? 823? ; 
8*0  + 23 =? 823? ;
  0 + 23 = ? 823 ? ;  No! ;  "0 + 23 = 23 " ; NOT "823" .

2)  The answers:  x = 10, -10 ; or, write as:  x = ± 10 .
_________________________________________________
To solve:
GIven:  8x² + 23 = 823 ; 
Subtract "23" from EACH SIDE of the equation:
_____________________________________________
           8x² + 23 - 23 = 823 - 23 ; 
to get:  
           8x²  = 800 ; 
Now, divide EACH SIDE of the equation by "8" ; 
          8x² / 8 = 800 / 8 ;
to get:  x² = 100 ; 
        Take the "square root" of EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ; 
          √(x²) = √(100) ;
             x  = <span>± 10 .
The answers:  x = 10, -10 ; or, write as:  x = </span><span>± 10 .
