City J is between City K and City L. You know the round-trip distance from City K to City L is 548 miles and the round-trip distance from City K to City J is 326 miles. Find the distance
between City J and City L. Justify your 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

the discriminant is 64 + 4*1*12 = 112

this is prime.

it would be 6xy and -16xy.
