Answer:
12 x P
Step-by-step explanation:
We know that the distance to the park is 1 mile. The distance is the same if he travels the same way back home, which we are assuming is what happened.
The distance traveled back and forth: 1 + 1 = 2 miles
We can subtract to find how many miles he still needed to walk: 5 - 2 = 3 miles.
To find how many times Josh walked around the trail, we can divide: 3 / 1/2 = 6 laps around the trail which is equal to 3 miles.
Check our answer: 3 + 2 = 5 (true)

Answer: x = {1, 2}
<u>Step-by-step explanation:</u>
x⁶ - 9x³ + 8 = 0
Let u = x³
⇒ (x³)² - 9(x³)¹ + 8(x³)⁰ = 0
⇒ u² - 9u + 8 = 0
⇒ (u - 1)(u - 8) = 0
⇒ u = 1 or u = 8
Replace u with x³
x³ = 1 or x³ = 8
Take the cubed root of each side
x = 1 or x = 2
One equation that could be used would be t = 25-12
