Answer:
The man traveled 20km by train.
Step-by-step explanation:
If x is the distance he traveled by train, you can write this equation to represent the situation:

Then, you can simply solve for x:

The man traveled 20km by train.

Answer:

Step-by-step explanation:
Wouldn't mikhail be 22?
if mikhail's age = 22 and gabrielle is twice that then gabrielle = 44
22
+44
_____
66
4x^4+x3-2x^2-6x+2
step by step:
(1): "x2" was replaced by "x^2". 2 more similar replacement(s).
2. ((((4•(x4))+(x3))-2x2)-6x)+2 (equation at the end of step 1)
3. equation at the end of step 2:
(((22x4 + x3) - 2x2) - 6x) + 2
4. polynomial roots caclulator:
3.1 Find roots (zeroes) of : F(x) = 4x4+x3-2x2-6x+2
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is 2.
final result:
4x4 + x3 - 2x2 - 6x + 2
