I put 30p so please answer the 4 pages ((If you can do it((please))))

Pg. 1

Your answer is the second option. They are equivalent and x = 5 for the second expression is 14. 

Pg. 2

Absolute value of any number is the the positive version of that number so your answer is the third option, 9

Pg. 3

Your answer is the third option. The second expression when x = 2 is 12. If you simplify the two expressions by combining like terms, they are not the same and thus are not equivalent. 

Pg. 4

Third option yet again. When you plug in x = 2, the value is 8. Combine like terms and you'll find they are not the same.
