If a square has a side of 12xy+1, it’s perimeter is:

48xy+4

Step-by-step explanation:

Because we know that a square has 4 sides, we can multiply this expression by 4, thus ending in 48xy+4. Hope this helps :)

For this case we have by definition, that the perimeter of a square is given by the sum of its sides. As the sides measure the same, then the perimeter is:

Where "l" represents the side of the square:

Then, they tell us that:

So:

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.
