Question

9x+10x²-x³

Answer 1

According to the solving  the perimeter of the given triangle is:

= -x³ + 13x² + 11x + 20

Describe the triangle:

Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.

What is the formula for the triangle's perimeter?

Simply summing the lengths of all the sides of a triangle yields its perimeter. A + B + C is the basic formula to determine the perimeter of a triangle with sides "a," "b," and "c."

According to the given data:

A = 9x+10x²-x³

B = -x² + 9x + 12

C = 4x²-7x+8

We know that the perimeter of the triangle is sum of all side of the triangle:

A+B+C

= (9x+10x²-x³) + (-x² + 9x + 12)+(4x²-7x+8)

= -x³ + 13x² + 11x + 20
