Apply the distributive property to create an equivalent expression. 4\left(3 + \dfrac14c - \dfrac12d\right) =4(3+ 4 1 c− 2 1 d)=

The equivalent expression is

Step-by-step explanation:

Using the distributive property we expand the expression

as follows:

which is the equivalent expression.

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
