teacher talkThis note just in from edublogs (who host this blog):
According to Teachers Count, the average teacher impacts 3000 students within a lifetime. How many will you impact this year? What kind of impact will your students have on others and the world? I hope to ease your first day back with the following tips and bookmarks.

H3 Note: If you are one of those “geeky” students reading this post, then let’s change the question – “What kind of impact will you have on your teachers this year?

PS: It does seem funny that, as American and most European schools are gearing up for a new school year, ones in the southern part of the globe are nearly halfway through Semester 2!

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)?]
