Answer:
1°F to 7°F is the best range to store ice cream.
Step-by-step explanation:
The ideal storage temperature of ice cream = 4°F
The allowance in the temperature is 3°F
So, the range of the store = 4°F ± 3°F
Now, 4°F + 3°F = 7°F
and 4°F - 3°F = 1°F
Hence, 1°F to 7°F is the best range to store ice cream.

So,


Answer: 18x2 + 69x + 65
Step-by-step explanation:
(3x + 5) (~6x + 13)
1. 3x(6x + 13) + 5(6x + 13)
2. 18x2 + 39x + 5(6x + 13)
3. 18x2 + 39x + 30 + 65
4. 18x2 + 69 + 65
