Which sets of measurements could be the side lengths of a triangle? Select each correct answer. Question 1 options:

2 cm, 2 cm, 2 cm

4 cm, 7 cm, 12 cm

5 cm, 8 cm, 13 cm

6 cm, 7 cm, 10 cm

5 cm, 5 cm, 12 cm

6 cm, 7 cm, 10 cm

Step-by-step explanation:

The sum of the two shorter sides must exceed the longer side.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
