AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9
        
                    
             
        
        
        
Answer:
The inequality required to express the above condition is   x     ≥    18.75
Step-by-step explanation:
Renata and her family go through an average of more than 15 cans of sparkling water each day.
The number of cases of 24 cans of sparkling water.
We can take the number of cases to be x.
Each case is said to cost $3.50.
An inequality for the number of cases that Renata's family go through in 24 days can be written as 
        x ≥  ⇒     x    ≥
           ⇒     x    ≥    ⇒   x ≥     18.75
         ⇒   x ≥     18.75
Therefore the inequality required to express the above condition is
 x     ≥    18.75
 
        
             
        
        
        
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x² 
     For x = a,
     f(a) = 8a²
     Now substitute these values in the expression,
      =
 = 
                   = 
                   = 
                   = 8(x + a)
b).  =
 = 
                       = 
                       = 
                       = (8h + 16x)
                       = 8(h + 2x)
 
        
             
        
        
        
I think you want a rounded answer. The answer would be 200,000
        
             
        
        
        
The given polyn. is not in std. form. To answer this question, we need to perform the indicated operations (mult., addn., subtrn.) first and then arrange the terms of this poly in descending order by powers of x:
P(x) = x(160 - x) - (100x + 500)
When this work has been done, we get P(x) = 160x - x^2 - 100x - 500, or
P(x) = -x^2 + 60x - 500
So, you see, the last term is -500. This means that if x = 0, not only is there no profit, but the company is "in the hole" for $500.
