Question

What is the perimeter of the triangle expressed as a polynomial?​

Answer 1

11x -4

Explanation:

We add up all the sides to find the perimeter of the triangle

4x+1 + x-7 + 6x+2 = Perimeter

Combine like terms

4x+x+6x +1-7+2

11x -4

Answer 2

11x -4

Explanation:

The perimeter (P) is the sum of the three sides, which is ...

P = (4x +1) +(x -7) +(6x +2)

P = (4+1+6)x +(1 -7 +2)

P = 11x -4
