Answer:

Step-by-step explanation:
Longest side of ∆ = 2a = 6.2 cm
If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is
The sum of the 3 sides = perimeter = 14.5 cm
Thus,

Plug in the values of a and b

The equation that can be used to find the side lengths is 
Answer:
Step-by-step explanation:
3(2x - 8) + 4x = -2(12 - 7x) - 4x
6x - 24 + 4x = - 24 + 14x - 4x
10x + 24 = 24 + 10 x
Step-by-step explanation:
The answer to your question is (D) 16. This is the answer because if count by 16's it goes 16, 24, 36, etc. since 24 is a multiple its could also be x
