Answer:
Plan B
Step-by-step explanation:
If you multiply 21 by $2.50 you get $52.5 then add $5 you get 57.5 and that's you outcome for Plan A
but if you multiply 21 by $1.50 you get $31.5 then add $24 you get $55.5 so the best and cheapest plan would be Plan B
The overall width of the path and garden is 12 feet.
The area of the entire garden and path is 12 x 12 = 144 square feet.
The path is 1 foot wide, so the garden would be 12 - 2 = 20 feet wide.
The area of the garden only would be 10 x 10 = 100 square feet.
The area of the path only = 144 - 100 = 44 square feet.
1 bag covers 9 square feet:
44 / 9 = 4.88
You would need 5 bags.
Answer:
x-3
Step-by-step explanation:
(x
2
−9)=(x−3)(x+3)
(x
3
−27)=(x
3
−3
3
)=(x−3)(x
2
−3x+9)
(x
2
−8x+15)=(x−3)(x−5)
∴ H.C.F. of (x
2
−9),(x
3
−27) and (x
2
−8x+15) is x−3.
