Answer:
x = -1
Step-by-step explanation:
You want ...
f(x) = g(x)
-2x -8 = 4x -2
-6 = 6x . . . . . . . . . . add 2x +2
-1 = x . . . . . . . . . . divide by 6
If he once traveled 36 hours and he takes 6 hour trips you do
10x3=30 so every six hours he takes 30 minute brakes then 36 divided by 6 equlas 6 you would do 30x6= the answer!!! (Btw i do 6th grade math)
You need to find the sum of the areas of the 6 sides.
That will be:
2*10*5+2*5*4+2*4*10=220
You can re-write this quotient this way :
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1
