What is the simplified form of the following expression? Assume a greater-than-or-equal-to 0 and c greater-than-or-equal-to 0

14 (RootIndex 4 StartRoot a Superscript 5 Baseline b squared c Superscript 4 Baseline EndRoot) minus 7 a c (RootIndex 4 StartRoot a b squared EndRoot)

7 a c (RootIndex 4 StartRoot a b squared EndRoot)
7 (RootIndex 4 StartRoot a b squared EndRoot)
Negative 7 (RootIndex 4 StartRoot a b squared EndRoot)
Negative 7 a c (RootIndex 4 StartRoot a b squared EndRoot)

You are making a blueprint of your bedroom and you plan to use a scale factor of 18 . the actual width of your room is 14 feet and the actual length of your room is 16 feet. determine the width and length of your room on the blueprint. on the blueprint, your room will have a width of feet and a length of feet.

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.
