x + 2y + 6y

x + 8y

Answer 2

Answer:

step by step explanation :-

\begin{gathered}perimeter \: of \: triange = sum \: of \: all \: sides \\ \\ = (x - 2y + 3z) + (5x - 2y) + (4x + 6y + 9z) \\ \\ = (x + 5x + 4x) + ( - 2y - 2y + 6y) + (3z + 9z) \\ \\ = 10x + ( - 4y + 6y) + 12z \\ \\ peimeter = 10x + 2y + 12z \\ \\ so \: the \: perimeter \: of \: triangle \: is \: 10x + 2y + 12z\end{gathered}

perimeteroftriange=sumofallsides

=(x−2y+3z)+(5x−2y)+(4x+6y+9z)

=(x+5x+4x)+(−2y−2y+6y)+(3z+9z)

=10x+(−4y+6y)+12z

peimeter=10x+2y+12z
