The answer should be 0.001703578
6+y
Since increased (key word) means addition.
6 rows x 9 squares = 54
there are a total of 54 squares
(12x^3-4x^2+8x)/(-2x) The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:
-6x^2+2x-4 and we can now also factor out -2
-2(3x^2-x+2)
