Option C: 17+3x is the right answer
Step-by-step explanation:
Given
Side 1 = s1 = 4
Side 2 = s2 = 13
Side 3 = s3 = 3x
[tex]Perimter = s_1+s_2+s_3\\= 4+13+3x[/tex]
The numbers will be added. As the third side contains a variable, it cannot be added to numbers
so,
[tex]P = 17+3x[/tex]
Hence,
Option C: 17+3x is the right answer
