Answer:
K is 3.4 feet
Step-by-step explanation:
To find the perimeter of the octagon, we add up the lengths of all the sides
For this particular octagon;
7 * k + 3.9 = 27.7
7k + 3.9 = 27.7
7k = 27.7-3.9
7k = 23.8
k = 23.8/7
k = 3.4 feet

2x+5=15 or 2x+5=-15
2x=15-5 or 2x=-15-5
2x=10 or 2x=-20
x=5 or x= -10
