-x -7y = 14
-4x -14y =28

answer: none of these answers are correct only the second half is

step-by-step explanation:

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.

to find perimiter, add all the sides.

60 5/6 + 54 1/3 + 59 1/3 + 56 1/6.

goup like terms:

(60 5/6 + 56 1/6) + ( 54 1/3 + 59 1/3) = 117 + 113 2/3

56 + 60 =   116. 5/6 + 1/6 = 6/6 = 1/ 116 + 1 = 117

54 + 59 = 13. 1/3 + 1/3 =2/3. 13 + /3 = 113 2/3    

117 + 113 2/3 = 230 2/3

answer: 230 2/3
