Fit for Math!

June24

A survey of Spanish students has found a close link between fitness and grade levels.

fitnessThe study sample included more than 2,000 Spanish children and teenagers, aged from six to 18, with detailed information on physical fitness, body composition, and academic performance. The researchers found cardio-respiratory capacity and motor ability, both independently and combined, were related to academic performance. However, the link between academic performance and physical fitness was stronger for speed, agility and coordination. In contrast, children and teenagers who weren’t as fit or dextrous had lower grades. Read more here. (pic by H3)

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)?]
