Add or subtract as indicated. Express your result in simplest form.
(4y)/(y^2+6y+5) plus (2y)/(y^21)
My answer is: (6y)/((y+5)(y1))

Geometry. Refer to the triangle in the figure. Find an expression that represents its perimeter
It has the following: (3)/(4x), (5)/(x^2),(1)/(x^2)
My answer: by using the formula for permiter that is P=a+b+c
My answer for this is: (3(8+x))/(4x^2)
first: I don't agree with the denominator: shouldn't it be
(y+1 )*(y1)(y+5)
second correct.
