Mary is building a rectangle enclosure for all her chickens. The length of the enclosure is 22.5m and the width is 13.2m. If she already has 30m of fencing, how much more does she need?

41.4 meters

Step-by-step explanation:

22.5 + 13.2 = 35.7

35.7 × 2 = 71.4m (because of the other 2 sides of the rectangle)

71.4-30=41.4m

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.
