Answer: x^3 - x^2 +5*(x - 2) = 0 <=> ( x^2)*(x - 2) +5*(x - 2) = 0 <=> (x - 2)*(x^2 + 5) = 0 =>
x = 2

Answer:
66 2/3 words per minute
Step-by-step explanation:
To convert 800 words in 12 minutes to a unit rate, you need to divide 800 and 12 by 12. Since 80012=2003=6623

The number of hours Tom took a trip of 1,020 miles is 3 hours.
Given that, Tom took a trip of 1,020 miles.
The speedformula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.
Tom traveled by train at 55 miles an hour and the same number of hours by plane at 285 mph.
Let the number of miles travelled by train be x. Then, the number of miles travelled by plane be 1020-x.
Time = x/55 = (1020-x)/285
⇒ 285x = 55 (1020-x)
⇒ 285x = 56100 - 55x
⇒ 285x + 55x = 56100
⇒ 340x= 56100
⇒ x = 56100/340
⇒ x = 165 miles
So, time = 165/55 = 3 hours
Therefore, the number of hours Tom took a trip of 1,020 miles is 3 hours.

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
m(x) = 2(x + 4)² - 8 ← is in vertex form
with vertex = (- 4, - 8 ) → A
