Will give brainliest write an expression for the perimeter of the triangle shown below: a triangle is shown with side lengths labeled 0.5x + 9, 3x, and (-3.4x) - 25. 6.9x − 16 6.9x + 16 0.1x − 16 0.1x + 16

0.1x - 16  (c)

Explanation: The perimeter is the sum of all three sides of the triangle. Since the three side are 0.5x + 9, 3x, and (-3.4x) - 25, the sum is as follows:

0.5x + 9 + 3x + (-3.4x) - 25 = 0.1x - 16
