Samuel needs to mail a package to his friend in New York. He places an address label with length represented by the function L(w) = 3x³ + 2x² - 4x + 5 and width represented by the function w(x) = x + 2. Which of the following statements is true about the area of the label? Select all that apply. 1. A(x) = L(x) + w(x)

2. The resulting polynomial for a(x) will be a 4th degree polynomial

3. L(x)=A(x) divided by w(x)

4. The resulting polynomial for A(x) will have a leading coefficient of 6

5. A(x) = L(x) * w(x)

I know what the answers are its B, C,D but i need work showing how I got to that conclusion
