Use algebra tiles to model the expression. Then, use the model to help you write an equivalent expression, and complete the statements. 3(x + 1) Model the expression as ✔ 3 groups of x + 1. There are ✔ 3 x tiles. There are + 1 tiles. The equivalent expression is

1.  3

2. 3

3. 3

4. 3x+x

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
