The correct answer would be -4
explanation:
2x-5<-12, add 5 to both sides so then you get 2x<-8, then divide by two, x<-4.
Answer:C.no solution

100% correct. ツ
Answer:
I would say option C.
A and B are not independent events because P(A|B)≠P(A) .
Step-by-step explanation:
We know that: P(A|B) = P(AandB)/P(B)
now, we can plug values that were given.
P(A|B) = 0.15/0.9
P(A|B) = 0.16666
but we have P(A)=0.5
We can see that both are not equal.
P(A|B) ≠ P(A)
So, A and B are not independent.
Value? Unclear what you mean. i think you're asking to multiply x(5x)(3x+12). That won't give you a value, but rather an expression.
x*5x comes to 5x^2.
Then 5x^2(3x+12) comes to 15x^3 + 60x^2 (answer)
