Use the distributive law to multiply. 3(4x + 5y + 6)

12x +15y+18

Step-by-step explanation:

3(4x + 5y + 6)

3*4x + 3*5y+3*6

12x +15y+18

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

it is probably the graph on the bottom right.
