Will you will have to babysit like 6 hours cause you got pay only 9 from the car wash and 10x5=50 + the 9 car wash is 59 only and u will need the .95 so u will need 6 hours of babysitting for the .96
My estimate is about 200$ but I did it in my head so you might want to check on a calculator. :) hope this helped!
Answer:
D is the answer
Step-by-step explanation:
The first and the difficult thing is you need to tell that
x^2-4xy+4y^2 = ( x - 2y )^2
so from question you know 3x - 6y = x - 2y = 9z
finial : ( x - 2y )^2 = ( 9z )^2=81z^2
so the answer is D . Hope this would help you .
