Question

The three sides of a triangle are 2x + 3y - 6z, 4y –z + 7x and

12x + 2y + 10z. Find the perimeter.​

Answer 1

Answer:

= 3 ( 7 X + 3 Y - Z)

Step-by-step explanation:

Here, values of X, Y and Z are not given. But perimeter of triangle is the sum of all of its side.

P = 2 X + 3 Y - 6 Z + 4 Y - Z + 7 X + 12 x + 2 Y + 10 Z

= 21 X + 9 Y + 3 Z

= 3 ( 7 X + 3 Y - Z)
