Convert the meter distance to KM so thaey are all the same measurement:
1 meter = 0.001 km
400 m x 0.001 m/km = 0.4 km
Now add all three distances:
Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.
The answer is B.
Answer:
whats the question
Step-by-step explanation:
Answer:
y = 6 or 8
Step-by-step explanation:
1. Subtract the constant:
y^2 -14y = -48
2. Add the square of half the y-coefficient:
y^2 -14y +49 = -48 +49
Write as a square, if you like:
(y -7)^2 = 1
3. Take the square root:
y -7 = ±√1 = ±1
4. Add the opposite of the constant on the left:
y = 7 ±1 = 6 or 8
The solution is y = 6 or y = 8.
