Answer:
see below
Step-by-step explanation:
8(n + 2)(n + 4) = 1,144
FOIL
8(n^2 +2n+4n+8) = 1144
Divide each side by 8
8/8(n^2 +2n+4n+8) = 1144/8
(n^2 +2n+4n+8) = 143
Combine like terms
n^2 +6n+8 = 143
Subtract 143 from each side
n^2 +6n+8 -143= 0
Combine like terms
n^2 +6n -135 =0
Factor
What two terms multiply to -135 and add to 6
-9*15 =-135
-9+15 = 6
(n-9) (n+15) =0
Using the zero product property
n-9 =0    n+15=0
n = 9   n=-15
The length cannot be negative so n = -15 cannot be  a solution
n =9
 
        
                    
             
        
        
        
100 
because 100 times 4 is 400.
 
        
                    
             
        
        
        
Using the Pythagorean theorem we get:

Simplifying the above result we get:

Subtracting 64 from the above equation we get:

Therefore:

We  have to realize a simple rule of three  
if 1 cup of corn------------------------- > 7.87 g of fat
2.5 cup--------------------------- X
X=2.5*7.87=19.675 gr
the answer is 19.675 grams of fat in 2.5 cup of corn
