Great Galloping Galaxies in 4GB!

The Hubble Space Telescope of ESA has captured the largest and sharpest image of the Andromeda galaxy that lies at a distance of 2.5 million light years. The image was first released at the meeting of 225th meeting of American Astronomical Society (AAS) in early January and is comprised of 1.5 billion pixels. It uses […]

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)?]
