Answer:
18
Step-by-step explanation:
if AB : BC : AC is 3 : 4 : 2 and BC = 8 then AB = 6 and AC = 4
To calculate the perimeter of the triangle we add all side lengths up
4 + 6 + 8 = 18
Answer:

Step-by-step explanation:
To solve this operation we need to find the common multiple of both denominators and solve for a.

Thus, the solution is 7(a -1) / (a+2)(a-5)
