Which expression is equivalent to (6c+9)(6c-9)? 36c2-81
36c2 + 54c-81
o 12c
36c² +81
D Question 2
What’s the answer???

36c2-81

Step-by-step explanation:

It's a difference of squares so you Florida it (FL) do first and last to get 36c2-81

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.
