17. Expand the following expression completely using the Binomial Theorem (Pascal's Triangle) (2x-y)
A. x3 - 3x2y + 3xy2 - xy?
B. 8x3 - 12x²y - 6xy2 - y2
C. 8x3 - 12x2y + 6xy2-y3
D. 2x2 - 6xły + 6xy?- y3

answer: i believe its b. if you sound out the sentences that sounds wrong.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.
