According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let the third side be x.

Given sides: 6 cm and 14 cm

The third side x must satisfy:

1. x + 6 > 14 => x > 8

2. x + 14 > 6 => x > -8 (this is always true since x is positive)

3. 6 + 14 > x => x < 20

Combining these conditions:

8 < x < 20

Pressure is inversely proportional to area (Pressure = Force / Area), and the pointed end has a much smaller area.

Thus, the same force produces greater pressure at the pointed end, allowing it to pierce surfaces easily.

Explanation

Given:

ab + bc + ca = -4

a² + b² + c² = 17

Using the identity (a + b + c)² = a² + b² + c² + 2(ab + bc + ca):

(a + b + c)² = 17 + 2(-4)

= 17 - 8

= 9

a + b + c = ±√9

= ±3
