Answer:
1. no triangle
2. unique triangle
3. unique triangle
4. unique triangle
5. no
Step-by-step explanation:
1.) if you add the smallest numbers, they are less than the biggest: , so these can't be measures of a triangle
2.) because the ASA rule (angle-side-angle)
3.) This is a right triangle. Also, you have a 60° angle and a 90° and a side, so a triangle is proven with the ASA rule
4.) because you are given three sides and the two smallest sides are greater than the longest.
5.) A unique triangles is formed if you know all three sides (SSS), two sides and the included angle (SAS), or two angles and the included side (ASA). We are given three degree measures. Although the measures do make a triangle, with only the measures of the angles, we can make many different triangles, all similar to each other.

Answer:
In a quadratic equation of the shape:
y = a*x^2 + b*x + c
we hate that the discriminant is equal to:
D = b^2 - 4*a*c
This thing appears in the Bhaskara's formula for the roots of the quadratic equation:
You can see that the determinant is inside a square root, this means that if D is smaller than zero we will have imaginary roots (the graph never touches the x-axis)
If D = 0, the square root term dissapear, and this implies that both roots of the equation are the same, this means that the graph touches the x axis in only one point, wich coincides with the minimum/maximum of the graph)
If D > 0 we have two different roots, so the graph touches the x-axis in two different points.
