I suppose we are to determine the proportionality constant of the variation. The equation for this proportionality is,
y = kwx / z
Substituting the known values,
320 = k(6)(20)/3
The value of k from the equation is 8.
Hello,
(x-1)(x-2)(x+3)²=(x²-3x+2)(x²+6x+9)
=x^4+3x^3-7x²-15x+18
Answer A
We can actually see that the statements that are true are:
A. x = 1 is a solution.
C. x = –1 is a solution.
<h3>What is rational equation?</h3>
Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.
We can see then that:

It's clear that: x ≠ 0 and x ≠ -6.
Looking for the LCM of the left hand side, we will have:

So, we will see that left hand side and right hand side are equal.





or

So, we can see that options A and C are correct.
