While making a book cover, anwar uses enough material to cover the front, back, and spine of the book. he adds an extra 20 square inches more to the surface area to allow for an overlap. how many square inches of paper will anwar use to make a book 11 inches long, 8 inches wide, and 1 inch high?

do you have the measurements?

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.
