Pls pls pls pls pls help​

we can write a ^1/2 as a^-1 so now

(a^-1 - a^-1) (a^-1 + a^-1)

Step-by-step explanation:

here (a-b) (a+b) = a^2+ b^2

so

use that formula and solve

or ya I won't solve all cuz i have give you the hint

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and

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.
