To find the perimeter, we need to add up the lengths of all three sides.
The first side is (3q+1) centimeters.
The second side is (5q-3) centimeters.
The third side is (r-9) centimeters.
Adding up the lengths of the three sides, we get:
(3q+1) + (5q-3) + (r-9)
This simplifies to:
8q - 8 + r - 11
So, the expression that represents the perimeter of the triangle is:
8q + r - 19

8z+9
To find the value of the expression 8z + 9 when z = 6, we substitute z with 6:
8(6) + 9
Multiplying 8 and 6:
48 + 9
Adding 48 and 9:
57
Therefore, when z = 6, the value of the expression 8z + 9 is 57.
