Chris says that he can find the surface area faster by thinking of the box as a triangular prism on top of a
rectangular prism. He finds the surface area of each one
and adds them together. Does his method make sense?

it is true

step-by-step explanation:

all the combinations add up i used   calculator

any options?

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.

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.
