on timed test! The graph of a line relates the volume as measured in gallons with its approximate equivalent volume measured in liters. Two points on the line are (0,0) and (5, 19) where the value of x is the volume in gallons and the value of y is the approximate volume in liters.

according to the graph of the line, 12 gallons is equivalent to Aproximentely how many liters?

a. 3 liters
b. 4 liters
c. 46 liters
d. 60 liters​

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

answer: #1 ads up by 8 and i don't know #2
