I have example problems I need help working on?

I have practice problems I am working on to prepare for my test. If anyone can show me how you solved the problems with explanation, it would be helpful.

Problem:

Evaluate. | –9 | + | 5 | + 2(-9)

Problem:

Evaluate. 5 • 6 (to the second)2 – 8 • 8

Problem:

Write an algebraic expression using the variable x.

“The product of 5 less a number and 4 less than twice the same number.”

Any help with these types of problems would be great. None of these are homework/test problems, just practice. Answers will be used for reference only. Thanks.
