Which expression is equivalent to 36a-12b 4(6a-9b) 4(8a3b) 4(9a+3b) 4(9a-3b)

d). 4(9a - 3b)

Step-by-step explanation:

a). 4(6a-9b)

= 24a - 36b

b). 4(8a-3b)

= 32a - 12b

c). 4(9a+3b)

= 36a + 12b

d). 4(9a - 3b)

= 36a - 12b

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.
