What are the zeros of the following quadratic equation and how do you know? x^2+x-6=0
A. The zeros are (-2,3). I know these are my zeros because they are the x-intercepts.

B. The zeros are (-2,3). I know these are my zeros because I typed the quadratic into poly solve.

C. The zeros are x=2 and x= -3. I know these are my zeros because they are the x-intercepts.

D. The zeros are x=2 and x= -3. I know these are my zeros because I typed the quadratic into poly solve.

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.
