What kind of mathematics is this?
b) 8
they were asking you about the rate of increase in students per year
so you take increase in students/years= (224-120)/(2005-1992)=104/13=8
You start off by multiplying the second bracket by -1 to get rid of the bracket.
So,
(2x3 + x2 - 4x) - 9x3 + 3x2 =
2x3 +x2 - 4x - 9x3 + 3x2 =
(2x3 - 9x3) + (x2 + 3x2) - 4x =
-7x3 + 4x2 - 4x
