Answer:
x = 4 ± 5i
Step-by-step explanation:
Just use the quadratic formula (ax²+bx+c=0) like you would for every other quadratic equation. Substitute i² for -1 when you get the square root of a negative number.
a = 1
b = -8
c = 41
Solution is x = (8 ± √(64-4·41)) / 2
x = 4 ± (√-100) / 2
x = 4 ± (√-25·4)/2
x = 4 ± √-25
x = 4 ± √(25i²)
x = 4 ± 5i
Answer : 2880.68274 miles/hour
1 foot = 0.000189394 miles
4225 feet = 0.000189394* 4225 miles
distance traveled in 1 second = 0.000189394* 4225 miles
distance traveled in 1/3600 hours = 0.000189394* 4225 miles
distance traveled in 1 hour = 0.000189394* 4225 * 3600 miles
Speed is = 2880.68274 miles/hour

Answer:
the answer would be 217 [degrees]
Step-by-step explanation:
Since m<1 and m<2 are next to each other, they are adjacent. Adjacent angles must share a common side which is m<W. This means they have to be added. m<1+m<2= m<XYZ
145+72=217
