Givens
h = 10
b = 4x^y + 2xy^2
Formula
Area = 1/2 b * h
Solution
Substitute the givens into the formula
Area = 1/2 * 10 * (4x^2y + 2xy^2)
Area = 5 * (4x^2y + 2xy^2) What to do next? I would remove the brackets
Area = 5 * 4x^2y + 5 * 2xy^2
Area = 20x^2y + 10xy^2 <<<< Answer
Also possible is to take out more common factors.
The common factor of 4x^2y + 2xy^2 is 2xy and what is left over is 2x + y
So you would have Area = 5*2xy(2x + y)

Answer:b
Step-by-step explanation:
You would have to multiply 6 bags of 6 gel pens together so 6x6, divide it by the friends so 6x6=36/9=4
Step-by-step explanation:
I think you mean that 10 cm³ of air are escaping every second.
and we start with a volume of 500 cm³.
V = 500 - 10t 0 <= t <= 50
because negative t (seconds) don't make any sense, and neither does a negative volume (for t > 50).
Selection C is the appropriate choice.
