Answer:
-y^2
Step-by-step explanation:
x(x-2y)-(y-x)^2=
Distribute
x^2 -2xy -(y-x)^2=
Foil
x^2 -2xy -(y^2 -2xy+x^2)=
Distribute the minus sign
x^2 -2xy -y^2 +2xy-x^2=
Combine like terms
-y^2
Highest number - lowest number = 8-3 = 5

Answer:
Step-by-step explanation:
50 + 30 = 80
1. let x be the number of months paid. 2. let 33x be the dollar value of the cost paid after x months (no initial fee yet) 3. let 33*5=165 be the cost paid on monthly basis for 5 months . But the total cost is $225 dollers after 5 months. the implies that the membership fee is 225 -165=dollers. 4. let TC be the total cost. 5. then the total cost TC=33x+60. 6. after 10 months , total cost TC= 33*10+60=330+60=390dollers.
