Alicia is programming computerized robotic arms to cut burlap for the 4th of July placemats. The placemats are to be rectangular in shape with an area represented by
45x2 - 71x - 150. The width of each placemat is represented by 5x + 6. The expression to
represent the length of each placemat can be determined by the formula,
length = area = width. Which expression can Alicia use in the programming to represent the
length of each placemat?

Which of the following would be a correct step in proving that triangle abc is congruent to triangle cda? a. use a protractor to measure the angles and show that all the corresponding angles are equal in measure. this will allow you to prove congruence by aaa. b. show that segment ab is parallel to segment cd and segment ad is parallel to segment cb. this will allow you to prove congruency by asa. c. show that is segment ab is perpendicular to segment ad. this will allow you to prove congruence by sas. d. none of the above.
