Answer:
Step-by-step explanation:
x=-2, x=3
---------------
x^2+5x+6=(-2)^2+5(-2)+6=(-2)(-2)-10+6=4-10+6=-6+6=0
x^2+5x+6=3^2+5(3)+6=9+15+6=24+6=30
---------------------------------------------------------------
x^2-x-6=(-2)^2-(-2)-6=4+2-6=6-6=0
x^2-x-6=3^2-3-6=9-3-6=6-6=0

Answer:
Acceleration = 3m/s²
Step-by-step explanation:
Here ,
Initial velocity = 30km/h
Final velocity = 0km/h
Time = 10s
Acceleration = ?
We know ,
A = v-u/t
or , A = 0-30/10
or, A = 30/10
A = 3m/s²
Therefore the acceleration is 3m/s²
Answer:
