3x^2 - 2x^2y + 2xy^2 + 4y^2 + xy^2 - y^2 + 2x^2y
= 3x^2 + 3y^2 + 3xy^2
answer
3x^2
3y^2
3xy^2
Answer:using the square root on both sides of the equation
Step-by-step explanation:
They are complementary
how?: well complementary angles are when you add two angles and equals to 90 degrees. when adding m1 and m2 you get 90 degrees.
Notice how the frontmost corner is the only corner stacked. Then, notice how the shape comes together without bending at all. This is impossible because the only way this could be a real shape is if the two angles on the left and right bend upward. Because this doesn't happen, the shape is impossible
