Answer:
3.5 centimeters.
Step-by-step explanation:
If the perimeter is equal to 11.5 centimeters, and we have the lengths of 2 sides, we can add them together and subtract that sum from the perimeter to get the value of the missing side length.
2.5 + 5.5 = 8
11.5 - 8 = 3.5
Therefore, the side length is equal to 3.5.
3.5
11.5 - 2.5 = 9
9 - 5.5 = 3.5
and scalene triange means none of the 3 sides are equal...
3.5 does not equal 5.5 or 2.5
D. - 1/6
M + 2/3 = 1/2
M = 1/2 - 2/3
D
D because it is always true
