Answer:
45 21 31
Step-by-step explanation:
The fence you have must fit the perimeter of the rectangle.
With 36 feet of fence, these are the rectangles that you can enclose:
1-ft x 17-ft . . . Area = 17 ft²
2 x 16 . . . Area = 32 ft²
3 x 15 . . . Area = 45 ft²
4 x 14 . . . Area = 56 ft²
5 x 13 . . . Area = 65 ft²
6 x 12 . . . Area = 72 ft²
7 x 11 . . . Area = 77 ft²
8 x 10 . . . Area = 80 ft²
9 x 9 . . . Area = 81 ft²
C=5/9 (62-32)
c=(5/9)*30
c= 150/9
c=16.666....
so c=16.6
The answer would be 6b-3c because a would cancel out and be 0
(x² + 16)(x² - 16)
= (x²)² - 16²
= x⁴ - 256
