Answer this 20 points and brainliest!

2x² + 2x

Step-by-step explanation:

Polynomials can be modeled using algebra tiles where square boxes each represent 'x²' and thin rectangles represent 'x'.  Smaller boxes would each represent a constant such as '2' or '3', however, in this representation there are no smaller boxes.  In this question, you have two large, square boxes that each represent 'x²' and two thin rectangles that represent a value of 'x'.  When we add x² + x² = 2x²; when we add x + x = 2x, so the overall polynomial expression is 2x² + 2x.
