Answer:
2/21
Step-by-step explanation:
you square 4/7 to get 16/49 then use keep change flip
you now have 16/49 times 7/24 then multiply 
 
        
             
        
        
        
Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
 is equal to
 is equal to  , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
 , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know  is just equal to 25, which means the simplified version of
 is just equal to 25, which means the simplified version of  is
 is  .
.
Then we can use this new representation to finish solving.
 , so the answer would be B
, so the answer would be B 
 
        
                    
             
        
        
        
Answer:
17.25
Step-by-step explanation:
im not sure with the answer without a photo.formula to find area is LENGTH×WIDTH so there u can find it
 
        
                    
             
        
        
        
1) Striangle = 1/2 * (12-8) * 4 = 1/2 * 4 * 4 = 8 km^2
2) Srectangle = 4 * 8 = 32 km^2
3) Sfigure = 8 + 32 = 40 km^2
Number C
