Multiply and simplify where possible: 4x(2y + 3z - 12) 8xy + 12xz - 48x
8x2y2 + 12x2z2 + 48
8xy + 12xz – 12
6xy + 12xz - 48

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual?

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
