Thank you:) Can you help with these other ones please? 18. The area of a rectangular barnyard is given by the trinomial 6x2 + 7x – 20. What are the possible dimensions of the barnyard? Use factoring. 2x – 5 and 3x + 4 –2x + 5 and –3x + 4 2x + 5 and 3x – 4 2x – 5 and 3x – 4 19. The area of a rectangular pool is given by the trinomial 2y2 + y – 3. What are the possible dimensions of the pool? Use factoring. (–y – 1) and (–2y – 3) (y – 1) and (2y + 3) (2y – 1) and (2y + 3) (2y + 1) and (y – 3) 20. A carpenter is putting a skylight in a roof. If the roof measures 10x + 9 by 7x + 7 and the skylight measures x + 5 by 3x + 3, what is the area of the remaining roof after the skylight is built? 67x2 + 115x + 48 73x2 + 151x + 78 70x2 + 133x + 63 3x2 + 18x + 15

OH! I was working the opposite I think. I have one more question I need help with. A refrigerator has a volume given by the trinomial y3 + y2 – 56y. What are the possible dimensions of the refrigerator? Use factoring. y, y + 8, and y – 7 y, y – 8, and y + 7 y + 7, y + 7, and y – 7 y + 8, –y + 8, and –y + 7
