37+n=p because all your doing is putting the numbers into a problem with the correct signs.

I got 6 units^2. So the answer is the second choice. ab/2 = 3*4/2 = 6.
        
                    
             
        
        
        
Try this option:
note, that distance between the parallel sides is shown via formula of area.
If it is possible, check the arithmetic.
 
        
        
        
16. 5x^3 y^-5 • 4xy^3
 20x^4y^-2
 20x^4 • 1/y^2
 =20x^4/y^2
17. -2b^3c • 4b^2c^2
 = -8b^5c^3
18. a^3n^7 / an^4 (a^3 minus a = a^2 same as n^7 minus n^4 = n^3)
 =a^2n^3
19. -yz^5 / y^2z^3
 = -z^2/y
20. -7x^5y^5z^4 / 21x^7y^5z^2 (divide -7 to 21 and minus xyz)
 = -z / 3x^2
21. 9a^7b^5x^5 / 18a^5b^9c^3
 =a^2c^2 / 2b^4
22. (n^5)^4
 n ^5 x 4
 =n^20
23. (z^3)^6
 z ^3 x 6
 =z^18
