Walter created this table to show a proportional relationship. Which values can be added to the table without changing the relationship? The Table::
1 batch of cookies = 2 cups of flour
3 batches of cookies = 6 cups of flour
5 batches of cookies = 10 cups of flour

A
2 cups of flour for 2 batches

B
4 cups of flour for 6 batches

C
8 cups of flour for 4 batches

D
12 cups of flour for 8 batches

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

is there supposed to be a diagram or a graph for this one? ?
