.5. You can use the polynomial identity (a - b) = a - 3a2b + 3ab2 - bº to determine the coefficients of the terms
in the expanded form of a binomial raised to the third power without cubing the
binomial. What is the coefficient of the
x-term in the expanded form of (2x - 5)?
A-125
8
B-60
D 150

Abilliard ball is struck by a cue. it travels 1 0 0 cm 100cm before ricocheting off a rail and traveling another 1 2 0 cm 120cm into a corner pocket. the angle between the path as the ball approaches the rail and the path after it strikes the rail is 4 5 ∘ 45 ∘ . how far is the corner pocket from where the cue initially struck the ball? do not round during your calculations. round your final answer to the nearest centimeter.
