Answer:
x=6
Step-by-step explanation:
Let us expand the left side:
3x+12 = 2x+ 4x -6
Let us then simplify the right side:
3x+12=6x-6
We can now put the same variables on one side to isolate x:
12+6=6x-3x
18=3x
x=6

Can I please know where angle x is located? there isn’t an x labeled on the triangle
Answer:

Step-by-step explanation:
Given
--- acceleration
--- final velocity
--- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:

Substitute values for v, u and a



Make t the subject


<em>Hence, the time taken is approximately 5.2 seconds</em>
