All year 12 students should be made to study intermediate mathematics if they want to enrol in a science, engineering or commerce degree at university, according to a national report by the Australian Academy of Science (AAS). “This is an absolutely critical issue. We’ve hit a pretty low point,”  said the director of the Australian Mathematical Sciences Institute […]

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
