Write down expressions for the perimeter of the triangle ABC and simplify it if AB = x, BC is 5 times more than AB, and AC is 3 cm less than BC.
Since BC is 5 times more than AB, then:
BC = 5 * x = 5x.
Since AC is 3 cm less than BC, then AC is equal to:
AC = 5x – 3.
The perimeter of a triangle is equal to the sum of its sides:
x + 5x + (5x – 3) = 11x – 3.
Answer: The perimeter of a given triangle is given by 11x – 3.
