For this case we have the following equation:
-16 = 16x ^ 2
Clearing x we have:
-16 / 16 = x ^ 2
x ^ 2 = -1
x = +/- root (-1)
Rewriting:
x = +/- i
Therefore, the solutions are:
x1 = i
x2 = -i
Answer:
this equation has two solutions:
x1 = i
x2 = -i
Answer:
45 minutes
Step-by-step explanation:
16 and 12 have the GCF of 4, so you divide both by 4. Then, since you know one hour is 60 minutes, you divide that by 4 as well to get a base unit of 15 minutes per 4 miles. Then, just take the number you got from dividing 4 by 12 (3) and multiply it by 15 to get 45 minutes.
