Answer: x=-2/5
Step-by-step explanation:
1. Expand: 3x+6=4-2x
2. Subtract 4 from both sides: 3x+6-4=-2x
3. Simplify 3x+6-4 to 3x+2: 3x+2=-2x
4. Subtract 3x from both sides: 2=-2x-3x
5. Simplify -2x-3x to -5x: 2=-5x
6. Divide both sides by -5: -2/5=x
7. Switch sides: x=-2/5

Answer:
x = 9
Step-by-step explanation:
Step 1: Look at graph
You can see that both ∠B's are the same. Therefore, both side lengths AD and CD are the same
Step 2: Set equations equal to each other
3x = 2x + 9
Step 3: Solve
x = 9
And we have our answer!

Answer:
Yes the car was speeding
Step-by-step explanation:
s = √(30fd) where
- s is the speed of the car in mph
- f is the coefficient of friction for the road
- d is the length in feet of the skid marks
Substitute d = 41.5 and f = 0.8 into the equation:
s = √(30 x 0.8 x 41.5)
⇒ s = √(996)
⇒ s = 31.55946768...
Therefore, for these data, the speed of the car was 31.56 mph (to the nearest hundredth)
The speed limit was 30 mph, therefore the car was speeding as 31.56 > 30
