Surface area = 2 pi (3x-2)^2 + 2 pi (3x -2) ( x + 3)
= 2 pi (9x^2 - 12x + 4 + 3x^2 + 7x - 6
= 2pi(12x^2 - 5x - 2)
Its D
Answer:
the first one is A, the second one is D.

12(16x+2) that's the answer
3) There are 12 inches in a foot, so 144/12 equals 12 feet- the distance above the floor. 12 goes into 40 about 3 times. 3 feet + 12 feet equals about 15 feet.
4) When you want to find the percentage of something, you would take the percentage and move the decimal place two spaces to the left. So 45% becomes .45. Then you would multiply that by the number of houses. .45 times 36 equals 16.2. Rounded to the nearest whole number, 16 houses display holiday lighting.
