The expression 13.26d + 9.20c can be used to find the total cost of d pounds of almonds and c pounds of cashews. How much does it cost to buy \ pounds of almonds and \ pounds of cashews?

The expression shows the price of one pound of almonds and one pound of cashews.

The number that we are to multiply to find the total cost of almonds is the cost of 1 pound of almonds which is $13.26 and the same goes for cashews, $9.20.

Now assuming we are to find the cost of 5 pounds of Almonds and 4 pounds of cashews, the total cost would be:

= (13.26 * 5) + (9.20 * 4)

= 66.3 + 36.8

= $103.10

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
