Halp!
what is the value of x in the equation 13 x-2(8 + 5 x) = 12-11 x?

Step-by-step explanation:

13x - 2 (8 + 5x) = 12 - 11x

You first have to distribute the parentheses...(which gives you...)

13x - 16 - 10x = 12 - 11x

Then you put the variables together...(which gives you...)

24x - 16 - 10x = 12

Then you add the rest of the variables... (which gives you)

34x - 16 = 12

After that, you add the "normal" numbers...(which gives you...)

34x = 28

Finally you divide them...(which gives you...)

     28             ( 28/34)

    34

(I think this is the answer, i did it on the computer so its hard, sryyy)

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
