How many triangles can be drawn with side lengths 3ft, 4ft, and 5ft

3

Step-by-step explanation:

The way to figure out if it is a triangle or not is by using the triangle inequality theorem. It says that the sum of 2 sides of the triangle must be larger than the third side. Therefore, there are 3 triangles that we can make with the side lengths of 3ft, 4ft, and 5ft.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
