True or False: A solution to a Linear Inequality is any point in the shaded
region?

True!

We know this is true because a linear inequality uses less than/greater than and less than or equal to/greater than or equal to. This means that as long as the answer fits into the given constraints (in a graph these constraints are shown as lines and dashed lines), it is true.

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
