Final answer:

The length of the missing side of a triangle with a perimeter of 12x-7 and one side that is x-8 is 11x + 1.

Step-by-step explanation:

Given that the perimeter of the triangle is 12x - 7and one of the sides is x - 8, we need to find the other side. Perimeter is the sum of all sides of the triangle. We can set up the equation as follows:

12x - 7 = x - 8 + (unknown side)

To solve for the unknown side, we need to subtract (x - 8) from both sides of the equation:

12x - 7 - (x - 8) = unknown side

Simplify this expression to solve for the unknown side:

11x + 1 = unknown side

So, the length of the missing side of the triangle is 11x + 1.
