need to get help with some algebra problems

Hello there, I have 5 algebra problems that I tried working on that I would like someone to look over and just let me know if I am working/solving these problems correctly or not. There are listed below…

1.) Simplify the expression of: 4(x-8)-8x = (I got 4x-8) is that correct or not? if not kindly explain what I did wrong and how I can fix the problem please.

2.) Simplify the expression of: 6(x-6)-9x= (I got 3x-6) is that correct or not?

3.) Find the area of the rectangle for 21 miles (2y+1)miles = (I got 22y+1 miles) is that correct?

4.) Subtract the polynominals for: (5a-6) – (a+3) = ( I got 4a – 3) is that correct?

and lastly # 5) Find the value of the polynominals for: 5x+5 = ( I got 40 is that correct)?

I look forward to hearing back from someone and am anxious to see how I did with solving these problems. Thanking you in advance for your time and help.
