Pi Day is getting closer!


Yes, we are again (see the last Pi Post) heading towards Pi Day (March 14 or 3/14 in the USA). Of course, in Australia and New Zealand we are able to celebrate a day earlier (on 14/03) than our North American mathematicians! We wonder whether Google will produce a unique Pi Day logo?

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)?]
