Answer:
Equation in square form:

Extreme value:

Step-by-step explanation:
We are given 

we can complete square 

we can use formula


now, we can add and subtract 5^2



So, we get equation as 

Extreme values:
we know that this parabola
and vertex of parabola always at extreme values
so, we can compare it with 

where 
vertex=(h,k)
now, we can compare and find h and k 

we get 
h=-5
k=-4
so, extreme value of this equation is 

 
        
                    
             
        
        
        
Answer:
-2.8h-26+5d
Step-by-step explanation:
So just combine like terms 
For the h, you’d get -2.8
For the d, you’d get 5
For the normal integer, -26
 
        
                    
             
        
        
        
Answer:
It is a 40% increase 
Step-by-step explanation:
So first of all the formula is 
New-old/old
Or rate of change/ original 
SO th new is 350
THe old is 210
350-210=140
140/350 which is old is 2/5
2/5 is 40 percent 
So 40 percent increase 
 
        
                    
             
        
        
        
Answer:
The square root of 196 is 14
Step-by-step explanation:
Prime factorization of 196:
Prime factors of 196 in pairs: 
Now square root of 196:
- √196 = √(2 × 2) × (7 × 7) 
- √196 = √(2 × 7)²
- √196 = (2 × 7)
-  = 14
Thus, The square root of 196 is 14
