Answer 10

I see it just fine.
you have to comine like terms
-1w + 4w^4 + y^4 - 3y^4 - 2w - 3w^4
I am going to seperate this so you can see the like terms
-1w - 2w = -3w
4w^4 - 3w^4 = w^4
y^4 - 3y^4 = -2y^4

so you are left with :
w^4 - 3w - 2y^4

What unit an lesson is this

Answer 35

that you are doing @Rainbow_dashie

Answer 36

9x + 7 + 5x - 3 = 14x + 4
14x + 2 + 4x + 3 = 18x + 5

difference is : (18x + 5) - (14x + 4) -- distribute through the parenthesis
18x + 5 - 14x - 4 = 4x + 1
=================
1/0.25 = x/2 --- 1 serving to 0.25 liters = x servings to 2 liters
cross multiply
0.25x = 2 -- divide by 0.25
x = 8 servings
