Need asap plz solve 1/4-7/10p=1/20p show work will give brainiest

Move the variable to one side by finding common denominator

1/4 - 7/10p = 1/20p

5/20 - 14/20p = 1/20p

        + 14/20p  +14/20p

5/20 = 15/20p

Simplify

1/4 = 3/4 p

multiply both sides by 4, then divide both sides by 3

1 = 3p

1/3 = p

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
