FIQIS. Un Question 13 of 46 Which of the following demonstrates how the first 21 (on the left side of the triangle) is calculated using the combination pattern? 1 2 1 33 1 6 4 1 5 10 10 5 1 6 15 20 15 6 1 1 721 35 35 21 7 1​

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

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.
