Question 12 1 pts
Which system of equations requires the most work before solving it by applying the
elimination method?
O [x-12y = -2
[x+8y=-3
O [x+12y = 3
(12y - 9x = 6
None of the other answers are correct
O [9x - 12y = -6
1-2x-12y = 3
O (3x + 12y = 9
1-2x-6y=-21

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+
