Hurry I need some help, explain it too if you can Two students, Robert and Jacob, simplify the expression 3(?? + 4x - 1)-(2x + 5), as shown below.
Robert
Jacob
Step 1 | = 3x2 + 12x - 3 - (2x + 5)
Jacob = 3x + 12x-1-(2x + 5)
Step 2 = 37+12r-3-2x+5
Jacob = 3x2 + 127-1-2-5
Step 3
3P + 10x + 2
Jacob = 3.rº + 10x - 6
3. The first error made in the simplification of the expression shown above was made by
A. Robert in Step 1
B. Jacob in Step 1
C. Robert in Step 2
D. Jacob in Step 2​

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.
