-2y-8+4y−2y−8+4y
A)−2(y+4)+4y
B)4(−2+y)−2y
C)none above

( C ) "none above"

Step-by-step explanation:

first you start by combining like terms

-2y-8+4y-2y-8+4y

-8+2y-2y-8+4y

-16+4y or 4y-16 would be the max simplification!

hope that helps  

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
