The perimeter of this quadrilateral is 100 in. What is the length of the side not given ? ( 27 in, 23 in, 32 in,)

8

Step-by-step explanation: The perimeter of the quadrilateral = Sum of the length of three sides. After you add the three sides what is left. So 27 plus 23 plus 32 equals 92. 100 subtracted by 92 equals 8.

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
