12 is the answer because when you add the green and blue you get 5 and 5×4= 20 so you multiply the blue by 4 and the green by 4 and add them together which = 20. so 3×4=12 and 2×4=8 so your answer is again 12
For your first one it’s definitely 94$
Your answer would be 7y^(3)+32y^(2)+9
Reflex angle.
hope this helped!
