-3(x + 6) =
Simplify expression

3x +18

Step-by-step explanation:

use distributive property.

x=-6

Step-by-step explanation:

1.) Distribute the -3

-3x - 18

2.) Set the equation equal to zero and add 18 on both sides

-3x-18=0

-3x=18

3.) Divide both sides by -3

x=-6

Negative 6 is equivalent to X

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.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
