Question

14. Write an expression to represent the perimeter of the triangle below. Find the perimeter. Each side measures -3(3x + 5), 2x - 8 and 11x + 24

Answer 1

We can calculate the perimeter by adding all expressions to get the following:

`P=-3(3x+5)+2x-8+11x+24`

then, we can use the distributive property to get rid of the parenthesis and then add each similar term to get:

`\begin{gathered} P=-3(3x+5)+2x-8+11x+24 \\ =-9x-15+2x-8+11x+24 \\ =-9x+2x+11x-15-8+24 \\ =4x+1 \end{gathered}`

therefore, the expression that represents the perimeter of the triangle is 4x + 1
