Answer:
Step-by-step explanation:
1. The quadratic formula is shown below:
2. Given the quadratic equation given in the problem, you have that:
3. Therefore, when you substitute the values shown above, you obtain the following result:
- Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side;
So for this, we are applying the triangle inequality theorem. If any of the inequalities are not true, then this cannot be a triangle. (Let A = 7.7, B = 4.0, and C = 1.7)
<u>Since the second inequality is false, these lengths cannot form a triangle.</u>
