The area is 57 square feet.
Small rectangle is 4 x 3 which is 12.
Big rectangle is 7.5 x 6 which is 45.
Add both areas of the shapes and you get 57.
D, as it increases by one
Put the numbers in order...
4,5,6,6,7,8,9,9,10,10,12,12,14,15
Q1 = (6 + 6) / 2 = 12/2 = 6
Q2 (median) = (9 + 9)/2 = 18/2 = 9
Q3 = (12 + 12) / 2 = 24/2 = 12
Q3 - Q1 = 12 - 6 = 6 (this is actually the interquartile range (IQR)
Dylan is wrong because if you multiply that ratio times 2 it would be 6/2 not 7/2.
No it depends on the sum of the two numbers
