What is the value of (4 - 2)2 - 3 x 4? -20 -8 8 20

-8

Step-by-step explanation:

(4−2)(2)−(3)(4)

=(2)(2)−(3)(4)

=4−(3)(4)

=4−12

=−8

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.

b

step-by-step explanation:

the word superfluous means unnecessary
