Question

A triangle has three sides(4x),(2x-6),and(10-x). Using the variable x, write an expression to define the perimeter

Answer 1

5x+4

Explanation:

well the perimeter is the sum of all sides

so we have

`P=4x+2x-6+10-x\\\\P=(4x+2x-x)+(-6+10)\\\\P=5x+4`

Answer 2

P = 5x+4

Explanation:

To find the perimeter, sum the sides

A triangle has 3 sides

P = 4x+ 2x-6 + 10-x

Combine like terms

P = 4x+2x-x -6+10

P = 5x +5
