The dimensions, in feet, of a rectangle are represented by expressions, as shown in the diagram below. Which of the following expressions represents the perimeter, in feet, of the rectangle?

Question 3 options:

6n + 5

13n + 10

10.5n + 10

20n + 5

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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.
