8/m-9=6/m-8
what does m equal?
show clear steps!

8/m-9=6/m-8

Move -9 to the other side. Sign changes from -9 to +9.

8/m-9+9=6/m-8+9

8/m=6/m+1

Move +6m to the other side. Sign changes from +6m to -6m.

8/m-6/m=6/m-6/m+1

2m could also equal to : 1/2m

1/2m=1

Multiply by 2/1 for 1/2m and 1.

1/2(2/1)m=2/1(1)

Cross out 2 and 2, divide by 2. Cross out 1 and 1, divide by 1.

m=2

m=2

i don't even know man. edge inuity be messing with us. i had to ask a question too.

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+
