To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.
The GCF of 2y^2 and -4y is 2y
So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.
2y(y-2)
2y^2 - 4y in completely factored form is 2y(y-2)
        
                    
             
        
        
        
Answer:
40
Step-by-step explanation:
plug -8 into the x so 
f(-8)=(-8)^2-3(8)= 
=64-24=
=40
 therefore, f(-8)=40

Answer:
Tax = $12 Tip = $18 Total Cost = $130
Step-by-step explanation:
tax = tax percentage x amount
0.12 x 100 = 12
tip = tip percentage x amount
0.18 x 100 = 18
The Total Cost 
total cost = cost + tax + tip
100 + 12 + 18
Add them up and it would be
$130
