First divide by 3 because we don't want any factor in front of the x² when doing factorization:
3x² + 15x – 18 = 0 => x² + 5 - 6 = 0
Then find the two numbers that multiply to -6 and add up to +5:
x² + 5 - 6 = 0 => (x-1)(x+6) = 0
So the solutions are x=1 or x=-6, that's answer B.
60 times 1 or 30 times 2 idk
Total cars 12+54 = 66
Find percentage of minivans.
12/66 = 0.1818 or ~18%
~18% of 77
77* 0.1818 = 13.999 ~ 14 rounded
<span><span>tan^2</span>(x) is the answer.</span>
