Write a simplified expression for the perimeter of the triangle

Question

Side 1 is 2s+4. Side 2 is 4s+2. Side 3 is 3. What would be the perimeter of the triangle.

Answer 1

Perimeter = sum of sides

side 1 side 2 side 3

(2s+4) + (4s+2) + 3

combine like terms

(2s+4s) + (4+2+3)

6s + 9

Answer 2

Perimeter = Side 1 + Side 2 + Side 3

Perimeter = 2s + 4 + 4s + 2 + 3 Combine like terms

Perimeter = 6s + 9
