PLS HELP Which expression is equivalent to 20c−8d? 2( 0c+4d 2 times 10 c plus 4 d

4(5c−8d)4 times 5 c minus 8 d

4(5c−2d)4 times 5 c minus 2 d

c(20−8d)c times 20 minus 8 d

Third one third one third one

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.
