Two sides of a triangle are 12cm and 8cm. Complete the inequality to show the possible lengths for the third side. If the third
Nookie1986 [14]

The inequalities that represents the third side of the triangle is  x ≥ 4 or x ≤ 20

How to find the third side of a triangle?

The triangle inequality theorem states that that the sum of any two sides of a triangle is greater than or equal to the third side.

Therefore, the two sides of the triangle are 12 cm and 8 cm.

A triangle with sides a, b and x follows the principle below;

a + b ≥ x.

Therefore,

let

x = third sides

12 + 8 ≥ x

20 ≥ x

x + 8 ≥ 12

x ≥ 4

x + 12 ≥ 8

Therefore, the third third should be greater than or equals to 4 or less than or equals to 20

x ≥ 4 or x ≤ 20

from month 1 to 2 the difference in hour is 1.5.
Month 2 to 3 =  3.5 to 5 = 1.5
Month 3 to 4 = 5 to 6.5 = 1.5
Month 4 to 5 = 6.5 to 8 = 1.5

The answer is C. Linearly, because the table shows that hours increase by an equal factor for an equal increase in months. which is 1.5 hours per month.
