Answer 36
Step-by-step explanation:
So, to factor out the equation x²+12x+35, first multiply the first and last numbers.
1×35=35
So, you need to find the multiples of 35 that add up to 12.
So, you find 7 and 5. These two numbers are the magic numbers that will be used as the correct factored form of x²+12x+35, because:
>7×5=35
>7+5=12
So, using these two numbers, you get your factored form as:
(x+5)(x+7)
To find the cost of one stamp, divide the total cost by the total number of stamps bought:
9.20 / 20 = 0.46
Each stamp cost 46 cents.

Standard deviation (σ) = 2 hours
Assuming a normal distribution, for any given number of hours 'X', the z-score is determined by:
For X=30
For a z-score of -1, 'X' corresponds to the 15.87-th percentile of a normal distribution.
For X=34
For a z-score of 1, 'X' corresponds to the 84.13-th percentile of a normal distribution.
The percentage of the garages that take between 30 and 34 hours to erect is:

The percentage is roughly 68%.
