Answer:
3320in²
Step-by-step explanation:
heron formula = √s(s-a)(s-b)(s-c)
  when s = (a+b+c)/2 
s =  (16+35+25)/2 = 76/2 = 38
heron formula = √s(s-a)(s-b)(s-c)  =  √78(78-16)(78-35)(78-25) = √78(62)(43)(53) = √11021244 = 3319.82589905≈3319.8in²(nearest tenth)
 
        
                    
             
        
        
        
I think the answer would be the first one
        
                    
             
        
        
        
The factor of the polynomial 18x³ + 6x²y - 9x² - 3xy will be 3x(6x² - 2xy - 3x - y). Then the correct option is C.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The polynomial is given below.
⇒ 18x³ + 6x²y - 9x² - 3xy
Then the factor of the polynomial will be 
⇒ 18x³ + 6x²y - 9x² - 3xy
⇒ 3x(6x² - 2xy - 3x - y)

Set up an equation of ratios as shown below:
  h        24 ft        4
----- = ---------- = ---
  4          6 ft        1
Cross multiplying the 1st and 3rd fractions, we get h=16 ft (answer)
        
             
        
        
        
It is 22 cuz 5 * 2 is 10 and 10 * 2 IS 20 + 2=22
