5. a rectangle has an area of 30 square meters and a perimeter of 34 meters. what are the dimensions of the rectangle?

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

i believe the answer is the polygon, heptagon.

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.
