Darina [25.2K]

Answer:

Step-by-step explanation:

The quadratic formula would be the following...

x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}

where the original quadratic equation would be represented as follows

ax^{2} + bx +c = 0

Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.

\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}

That would be the correct order for the values.

Also, both triangles have different side lengths, one having 2 inches and another having 3 inches, thus they have different size.

Hence, the true statement about the two triangles is:

The two triangles are the same shape but not the same size.

Therefore, option B is correct.
