My answer is: (2(x+8))/(2x-5)

------------------------------------

Add or subtract as indicated. Express your result in simplest form.

(2)/(5w+10) Subtracted by (3)/(2w-4)

My answer is: (11w+38)/(10(4-w-w^2))

-------------------------------------

Add or subtract as indicated. Express your result in simplest form.

(3)/(x^2+4x+3) subtracted by (1)/(x^2-9)

My answer is : (2(x-5))/((x+3)(x-3)(x+1))

First: No. just add the l, h and multiply by two.

second

correct

Third: correct
