Answer:
c = -12
Step-by-step explanation:
Quadratic Standard Form: ax² + bx + c
Step 1: Write equation
3x² + 6x = 12
Step 2: Subtract 12 on both sides
3x² + 6x - 12 = 0
Here, we have the standard form of the quadratic. We see that our c = -12

Answer: 22.55 mph
Step-by-step explanation:
Let the speed of the train be n
4 × 62 = 248 which is the distance travelled by the car in 4 hours and the train travelled in 11 hours
11 × n = 248
11n = 248
n = 248/11
n = 22.55mph
