Step-by-step explanation:
1: we need to find how many cartons the roses will fill so
1368/28 = 48.857 cartons.
2: We can't have .857 of a carton, so we need 49 cartons to hold all the roses.
Answer:

Step-by-step explanation:
55-11(4)=2.75
2.75+11=13.75
13.75x4=55
Answer:
10 (8-x)(8+x)
Step-by-step explanation:
640-10x^2
Factor out 10
10 (64 - x^2)
Notice that inside the parentheses is the difference of squares
10 ( 8^2 - x^2) and a^2 - b^2 = (a-b) (a+b)
10 (8-x)(8+x)

Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
