Find BC please help ASAP!!

A. 31.4km
B. 26.6km
C. 25km
D. 30.7km

root631 will be hypotenuse

The choose (c)

C. 25km

Step-by-step explanation:

21²+14²=BC²

441+196=BC²

637=BC²

BC=25.2

BC=25 Km

d? maybe

step-by-step explanation:

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.
