6-93. Alex and Maria were trying to find the side labeled x in problem 6-92. Their work is shown below. Alex: I noticed that when I multiplied

by 3. the sides of the triangle gor longer."

Maria: "I remember that when we were dilating shapes in

Lesson 6.2.2, my shape got bigger when I divided by

A..A

4.A

8.3 = 24

8

= 24

a. Look at each student's work. Why do both multiplying by 3 and dividing by - make the triangles larger?

b. Use Alex and Maria's strategy to write two expressions to find the value of y in problem 6-92.
