I would really appreciate it if someone could answer this I will give a brainlist:)

x = 17

Step-by-step explanation:

Formula:

a² + b² = c²

8² + 15² = c²

64 + 225 = c²

c² = 289

c = 17

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.

answer: are you
