IF U ANSWER FIRST U GET BRAINLIEST (BUT HAS TO BE CORRECT)3/x=x/12

Correct answer is + or - 6

3/x = x/12

cross multiply

x^2 = 36

x = root 36

x = plus or minus 6

6

to solve this. = 3/x = x/12

=}. 3/x = x/12

by doing cross multiple

we get x^2 = 36

so, x=. √36

x=. 6

hope it helps

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.
