√216=
√(36*6)=6√6
Answer:
x = -2
Step-by-step explanation:
Pull out like factors :
-3x - 6 = -3 • (x + 2)
Solve : -3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : x+2 = 0
Subtract 2 from both sides of the equation :
x = -2
The distance between Car A and car B,When Car A crosses the start line is:
distance =speed car B* time
distance=(15 m/s)(3 s)=45 m
Distance traveled by car A =x, (when the car B is at the same distance from the start line)
time of car A=t
x=10 m/st ⇒ x=10t (1)
Distance traveled by car B=x
time of car B=t-3
x=15(t-3) (2)
With the equations (1) and (2) we make a system of equations:
x=10t
x=15(t-3)
We solve this system of equations:
10t=15(t-3)
10t=15t-45
-5t=-45
t=-45 / -5
t=9
t-3=9-3=6
x=10 t=10 (9)=90
Answer: The time would be 9 seconds for Car A and 6 seconds for car B and the distance would be 90 meters.
Answer:
they are congruent so e=44°
