2) a) Evaluate 2x' and (2x) separately when x = 8. b) On the lines below, explain why the expressions are evaluated differently.
3) A regular pentagon has a perimeter of 30x - 75. Find the measure of one side.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

its line 2 i just added the rest or else it wouldn't let me answer
