We have:
- 48 km ---------------- 6 liters of cng gas
- 112 km ---------------- ? liters of cng gas
So:
P/s: x is a quantity of cng gas will be needed to go 112 km.
Answer: 14 liters of cng gas
Ok done. Thank to me :>
A 2/3 pi x ^2 is the best choice
P(A|B) = P(A)*P(B) - P(A∩B)
Here, we have:
P(a 6 is chosen, given that a diamond was already chosen) = (1/4)(1/4)-(1/52) = 0.043
Answer:
x=2 is not a solution
Step-by-step explanation:
x^4 +2x^3 -x^2 -2x = 0
I will factor by grouping
x^4 -x^2 + 2x^3 -2x =0
Factor out x^2 from the first group and 2x from the second group
x^2(x^2-1) +2x(x^2-1) =0
Now factor out x^2-1
(x^2-1) (x^2+2x)=0
From the second term we can factor out an x
(x^2-1) x(x+2)=0
Using the zero product property
(x^2-1) =0 x = 0 (x+2)=0
x^2 =1 x=0 x=-2
Taking the square root
x=±1 x=0 x= -2
The solutions are -2,-1,0,1
Answer:
Step-by-step explanation:
The quotient of two numbers and can be written as , the first number mentioned being the numerator.
In this case, the first value mentioned is 5 more than a number y, which can be represented as . This is our numerator.
The second value mentioned is 3 times less than a number x, which can be represented as or . This is our denominator.
Thus, the quotient of these two numbers is
