We can’t go back in time, can we?


Hey, with Daylight Saving coming into effect, we lost an hour last night, but where did it go? I was taught that, in order to go back in time, you would need to travel faster than the speed of light (thanks Einstein). But, the physicists tell us, this is impossible, so we can’t have lost any time at all? No, I think this “daylight saving” is a myth. Check out this time article and see if you can figure it out:

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

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)?]
