Answer: (x + 2) × (x + 1)
Step-by-step explanation:
x^2 + 3x + 2
x^2 + 2x + x + 2
x(x + 2) + 1(x + 2)
(x + 1) (x + 2)
Answer:
(B)
Step-by-step explanation:
v^2 = v0^2 + 2ax
a = (v^2 - v0^2) / 2x
= (20^2 - 10^2) / 200
= 1.5 m/s
Answer:
The fourth graph.
Step-by-step explanation:
In all other pictures the time would need to go backwards. Time can only move in one direction.
Answer: x = - 111
Step-by-step explanation:
