your answer. (Explore Activity) 1. Is 3xy a monomial? mial. Give justification for Justify your answer. 2. Is 2xy +7x a monomial? Justify your answer. Classify each polynomial by its degree and the number of terms. (Example 1) 3. Sx-3y+7 4. 2xy-8x'y' Simplify each polynomial. (Example 2)- 5. 2-y+2y+7 7. 6a-5a+ 2d - 5d-8d 6. 2mm-11m +5mm + 2m 8. +10+5 - 77 Solve the problem by evaluating the polynomial. (Example 3) 9. Nate's architectural client said she wanted the width of every room in her house increased by 2 feet and the length decreased by 5 feet. The polynomial 2w-w-10 gives the area of any room in the house with w representing the room's width. The width of the kitchen is 16 feet. What is the area of the kitchen? ?
