Simplify √ 105 . a. 2√ 3 b. √ 105 c. 2√ 7 d. √ 42

The answer is the option B

Step-by-step explanation:

we have

we know that

so

substitute

-------> it can not be simplified

therefore

the answer is

----> the expression can not be simplified

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

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.
