Answer:
-91x² + 5x³ - 56x -15 = 0
Step-by-step explanation:
x² + 3x³ - 2x + 9 = 24 + 54x + 92x² - 2x³
x² + 3x³ - 2x + 9 - 92x² = 24 + 54x + 92x² - 2x³ - 92x²
-91x² + 3x³ - 2x + 9 + 2x³ = 24 + 54x -2x³ + 2x³
-91x² + 5x³ - 2x + 9 - 54x = 24 + 54x - 54x
-91x² + 5x³ - 56x + 9 - 24 = 24 - 24
-91x² + 5x³ - 56x -15 = 0

Answer:
JL is 111 miles
Step-by-step explanation:
When we talk of round trips, we mean the distance going plus the distance coming
To get the actual distance between the two places, we need to divide by 2
K to L is round trip 548 miles
K to L distance is 548/2 = 274 miles
K to J round trip is 326 miles
K to J distance is 326/2 = 163 miles
From what we have ;
KL = KJ + JL
274 = 163 + JL
JL = 274-163
JL = 111 miles
To justify our answer, we can see that J is between K and L
if we added the distance KJ and JL, we should get the distance KL
from the calculations we have made, we can see that this is correct and our answer is justified
