Answer:
-1.5
Step-by-step explanation:
4x² + 4x - 3 = 0
(2x + 3)(2x - 1) = 0

x = -3/2 or x = 1/2

km=kilometers
kilo=1000
1 km=1000meters
so
1/2km= 1/2 times 1000=1000/2=500meters
2. 1/4 km=1000/4=250 meters
3. 1/5 km=1000/5=200 meters
4. 2/5 km=2000/5=400 meters
5. 3/4 km=3000/4=750 meters
6. 1/8 km=1000/8=125 meters
