Homework for 8-29: page 11, items 17 and 18
9b. total area is L^2 which means L squared
10a. the graph is a line with a slope of 2
10b. the graph a line with a slope of 4, and you run out of room at the top
10c. the graph is not a straight line
13., 14., 15., 16:
a square is missing a smaller square
area of this level (the current level) is L squared
area of the previous level uses the L from the previous level
in math, "previous" means minus 1
if I am talking about level 42, the previous level is 42 minus 1 = level 41
if I am talking about level q, the previous level is q minus 1 = q - 1
area of the previous level is ( L minus 1 ) squared = ( L - 1 )^2
this level's area minus previous level's area = L^2 minus (L - 1)^2
the number of squares addes = L^2 - (L - 1)^2
