Question 719571: (y-3)/(y^2+y)-(y+1)/(2y)
Why is the answer:
-((y^2-7)/2y(y+1))
Because I was taught cross multiply for common denominator and so wouldn't it become, (2y)(y-3) - (y^2 + 1) (y+1) / (y^2+y)(2y)
Which then: 2y^2-6y - y^3+y^2+y+1 / 2y^2+2^2

Question 721070: A rectangular picture has a length of 2x+2 and a width of x-4 inches.
�Part A was asking to sketch and label the picture, which I did.
�Part B asked to write the expression in terms of x that represents the area of the picture and to simplify the expression. Here is my work:
(2x+2)(x-4)= 2x^2+2x-8x-8=2x^2-6x-8
=2(x^2-3-4)
I am not sure if my final expression is the correct answer. Can you please check?
�Part C was simple. I did it with no problem.
�Part D asks "You decide to frame the picture with a frame that is x units wide. Sketch the picture w/ its frame. Determine the dimension, in terms of x, of the framed picture."
