Answer is 120
AngNPQ=2*angNRQ=120
The answer would be C) because there are 11 possibilities of who can line up first, and after the first person, 10 possibilities, then 9, and so on. So you would need to multiply 11x10x9x8x...x1.
Try not to be bored. You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.
t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.
To find this value, do the following: Add 2t to both sides, and then subtract 9 from both sides. You'll end up with 7t = 7, which yields t = 1.
We call this the "solution" of the equation given.
The answer is 2X^3+12x^2+10x-24
