(x − 4)(x − 4)
Answer:
The factors of x^2 + 16 are (x - 4i) and (x + 4i).
Step-by-step explanation:
That'd be x^2 + 16, not x2 + 16.
First, an easier example: x^2 - 16 factors into (x - 4)(x + 4).
Note how (-4)(4) = -16.
The corresponding factors of x^2 + 16 are (x - 4i) and (x + 4i).
We can check this result through multiplication: (x - 4i)(x + 4i) = x^2 - 4ix + 4ix - 16(-1), or x^2 + 16.
Answer:
Option C: Prime
Step-by-step explanation:
It will take 10 people working 10 hours per day about 2.5 days to make 10 units of the product.
From the statement of the question; 15 people working 5 hours per day can make 30 units of a product in 10 days. Hence, the number of units that can be made in a day is;
Number of units per day = (15*5*10)/30
= 25 units/day
Now; if 10 people make 10 units, working 10 hours per day, it will take them x number of days.
x = (25*10)/10*10
x = 2.5 days
