Answer: Triangle 1: -6x + 105 Triangle 2: 20x - 30 Triangle 1 would have a greater perimeter if x = 5
Explanation:
The perimeter of a shape is the sum of all the sides. (Add them together)
Triangle 1:
17 + 6x + 4(-3x + 22)
Simplify:
17 + 6x -12x + 88
Perimeter = -6x + 105
Triangle 2:
24 + 5x + 3(5x - 18)
Simplify:
24 + 5x + 15x - 54
Perimeter = 20x - 30
If x = 5: (Plug in 5 for x)
Triangle 1:
If x = 5: (Plug in 5 for x)
-6(5) + 105
-30 + 105 = 75
Triangle 2:
20(5) - 30
100 - 30 = 70
75 > 70
Triangle 1 would have a greater perimeter if x = 5
Hope this helps!
