m=1 How? -2=9m-11 -2+11=9 9=9m 9/9=9m/9 m=1
9m=207 m=23
The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.
If: 9m=108 m=12 (I divided each side by 9 to isolate 'm').
9m - 14 = 8 9m = -8 + 14 9m = 6 m = 6/9 = 2/3 or 0.667
