Translate the sentence: On Thanksgiving, I ate too much food and fell asleep before I could watch the football game.

El día de la acción de gracias, comí demasiada comida y me caí dormido antes de que pudiera ver el partido de fútbol americano.

### Subject: Calculus

Take the integral of (x^2+2x+1).

Since the equation given to integrating only consists of pieces added together, you can integrate each piece separately. All of these pieces can be integrated using the power rule, so the integral of x^2 becomes (1/3)(x^3), the integral of 2x becomes (2/2)(x^2) or simply (x^2), and 1 can also be expressed as 1(x^0), so the integral would be x. Thus, the integrated expression would be (1/3)(x^3)+(x^2)+x.

### Subject: Physics

While you are on vacation, you realize that you left your refrigerator door open at home. When you return, will your house be colder, warmer, or the same temperature?

If you consider your home to be the system that you are focusing on, your home would be warmer due to the electrical work (by the refrigerator) being put into the system.
