Al made a tree house last summer. He started by making a model. The model included a window with a height of 1/3 inch and a width of 1/6 inch. The actual window had a height of 1/2 yard and a width of 1/4 yard. Was Al’s model an accurate representation? Explain.

step-by-step explanation:

wait this depends wether emily and zach how they are thinking.

yes they are the same.

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
