Geometry need asap extra points 4. use the law of detachment and the law of syllogism to draw a conclusion from the three given statements. if a person lives in santiago, then that person lives in brazil. if a person lives in brazil, then that person lives in south america. paul lives in santiago. select one: a. paul lives in brazil. b. paul lives in south america. c. if a person lives in santiago, then that person lives in south america. d. if paul does not live in santiago, then he does not live in brazil.

paul lives in south america

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

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
