Answer:

We conclude that Seth can make the model of the house on 9 different ways.

Step-by-step explanation:

We know that Seth uses 17 linking cubes to make a model house. The model house is in the shape of a rectangle and is one cube high.

We calculate how many different ways could Seth make the model of the house:

$C_8^9=\frac{9!}{8!(9-1)!}=9$

We conclude that Seth can make the model of the house on 9 different ways.
