Perimeter of the Triangle

$( {x}^{2} - 5x + 13) + (2 {x}^{2} - x + 19) + ( {x}^{2} + 3x + 21) \\ =(1 + 2 + 1) {x}^{2} + ( - 5 - 1 + 3)x + (13 + 19 + 21) \\ =(4 {x}^{2} - 3x + 53) \: units$

Step-by-step explanation:

Step 1: Define Inequality

3x + 1 < 10

Step 2: Solve for x

Divide 3 on both sides: x < 3

Here we see that any value x smaller than 3 would work as a solution to the inequality.
