The garden area is maximum when the enclosure is a square.
If a is the length of the side of the square then the length of the building is also a.
The perimeter length is 4a made up of 81+a feet, so 81+a=4a and 3a=81 making a=27 feet.
Answer: "
-2y³ + 3y²<span>
+ 27y " .

_______________________________________________________Using the completed chart below (image attached), we can write out the terms:
__________________________________________________ y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;
Then, we can combine the "like terms" ;
__________________________________________y³ − 3y³ = -2y³ ;
+9y² + 3y² − 9y² = + 3y² ;
___________________________________________________________to get: -2y³ + 3y² ; and bring down the "+27y" ;

Answer:
Step-by-step explanation:
1) 2 - (- 8) = 2 + 8 = 10
2) 2/5 + (- 1/5) = 2/5 - 1/5 = 1/5
3) We can find the common denominators through the least common multiple between the denominators:
4,12 | 2
2, 6 | 2
1, 3 | 3
1, 1 (2 × 2 × 3 = 12)
Then, 12 is the least common denominator.
4) 8 (1/4) + 10 (2/5) + 7 (5/8)
8 (1/4) = 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 4/4 + 1/4 = 33/4
10 (2/5) = 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 5/5 + 2/5 = 52/5
7 (5/8) = 8/8 + 8/8 + 8/8 + 8/8 + 8/8
+ 8/8 + 8/8 + 5/8 = 61/8
33/4 + 52/5 + 61/8
Employing the least common denominator:
4, 5, 8 | 2
2, 5, 4 | 2
1, 5, 2 | 2
1, 5, 1 | 5
1, 1, 1 (2 × 2 × 2 × 5 = 40)
(40 ÷ 4 × 33)/40 + (40 ÷ 5 × 52)/40 + (40 ÷ 8 × 61)/40
330/40 + 416/40 + 305/40
1051/40
