For this case we have the following expression:
 y2 - xy - 56x2
 Rewriting we have the factored expression, which is given by:
 (7x + y) (y-8x)
 Checking we have:
 7xy - 56x ^ 2 + y ^ 2 - 8xy
 y ^ 2 - xy - 56x ^ 2 (OK)
 Answer:
 The factored expression is given by:
 y2 - xy - 56x2 = (7x + y) (y-8x)
        
             
        
        
        
Answer:
Area of the base = 24 cm²
Height of the prism = 5 cm
Volume of the prism = 120 cm³
 
        
             
        
        
        
B is correct the devotion is only 2 compared to 4.
A is wrong because variate A has higher trees then variate B
C is wrong because deviation for A is 4 compared to 2 ( opposite of B)
D is wrong because 4th one is 10 for A and 13 for B. 10 is not greater than 13
        
             
        
        
        
Answer:
This cannot be solved but it can be simplified 
first we open the bracket 
so we have 
a²- abx/x = 2/3
next we cross multiply so it will be 3(a² - abx) = 2x
we get 
3a² - 3abx = 2x 
Next we factorise so we can get
3a(a-bx) =2x
