Which of the following possibilities will form a triangle? (5 points) a. side = 16 cm, side = 8 cm, side = 7 cm b. side = 16 cm, side = 9 cm, side = 7 cm c. side = 17 cm, side = 12 cm, side = 7 cm d. side = 17 cm, side = 11 cm, side = 5 cm

C. Side = 17 cm, side = 12 cm, side = 7 cm

Step-by-step explanation:

Three line segments can form a triangle, if the sum of any two lengths is greater than the third length.

In A), 8 + 7 = 15 < 16. So, A cannot form a triangle.

In B) 9 + 7 = 16 = 16. Hence, the lines are collinear.

In D) 11 + 5 = 16 < 17. So, D cannot form a triangle.

In C),

17 + 12 = 29 > 7

12 + 7 = 19 > 17 and

17 + 7 = 24 > 12

Hence, sides given in (C) can form a triangle.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
