0 or 1

Step-by-step explanation:

The answer to this depends on the version of the triangle inequality your author uses.

If you require ...

4 + 5 > 9 . . . . . false; NO TRIANGLES can be constructed

On the other hand, if you allow ...

4 + 5 ≥ 9 . . . . . true; ONE TRIANGLE can be constructed

Please consult your lesson materials to see which answer is expected.

Comment on a 4, 5, 9 triangle

A "triangle" with sides of lengths 4, 5, and 9 will look like a line segment. It will have zero height, hence zero area. Some authors don't consider such a figure to be a triangle.

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
