By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.
That gives us point (3,5) as the top of the parabola. So there you go, answer A.
You multiply all of them and you get 272!
3.42 multiply 45.60 by 0.075
Andy is wrong.
3/5 = 12/20
1/4 = 5/20
Add them up
12/20 + 5/20 = 17/20
17/20 is not equal to 4/9
Scene two because he has more than half of the lines
