Answer:
15x - 11 cm
Step-by-step explanation:
perimeter of triangle = sum of all its sides
so to find the perimeter, add all the sides
PERIMETER =
[tex](2x + 3) + (7x - 9) + ( - 5 + 6x)[/tex]
[tex]2x + 3 + 7x - 9 - 5 + 6x[/tex]
[tex]2x + 7x + 6x + 3 - 9 - 5[/tex]
[tex]15x - 11[/tex]
so the perimeter is 15x - 11 cm
