Question

If a triangle has sides of length x x + 2, and x - 4, what is the perimeter of the triangle in terms of x?
О 3х - 6
03x - 2
3x + 2
O 3x + 6

Answer 1

9514 1404 393

Answer:

(b) 3x -2

Explanation:

The perimeter is the sum of the side lengths:

P = (x) +(x +2) +(x -4)

P = (x +x +x) +(+2 -4)

P = 3x -2
