Answer:
StartFraction negative 1 Over k cubed EndFraction 
Step-by-step explanation:
3k / (k + 1) × (k²- 1) / 3k³
= 3k(k² - 1) / (k + 1)(3k³)
= 3k³ - 3k / 3k⁴ + 3k³
= -3k / 3k⁴
= -1/k³
StartFraction k + 1 Over k squared EndFraction 
(k + 1) / k²
StartFraction k minus 1 Over k squared EndFraction 
(k - 1)/k²
StartFraction negative 1 Over k cubed EndFraction 
= -1/k³
StartFraction 1 Over k EndFraction
= 1/k
 
        
             
        
        
        
2x4 + 2x2 = 32 because 2x4 equals 8 and then if you do 2x2 it equals 4.
