Answer: The correct option is
(D) 60.
Step-by-step explanation: Given that the number of stamps that Kaye and Alberto had were in the ration of 5:3 respectively.
After Kaye gave Alberto 10 of her stamps, the ration of the number of Kaye had to the number of Alberto had was 7:5.
We are to find the number of stamps that Kaye had more than Alberto.
Let the number of stamps Kaye and Alberto has are 5x and 3x respectively.
Then, according to the given information, we have
So, the number of stamps that Kaye had = 5 × 30 = 150
and
the number of stamps that Alberto had = 3 × 30 = 90.
Therefore, the number of stamps that Kaye had more than Alberto is
Thus, Kaye had 60 stamps more than Alberto.
Option (D) is CORRECT.

At first glance, it might be tempting to say this is a linear function, because we see linear terms (3x and –6x); however, these are multiplied together, so it's actually a quadratic.
We need to expand the function (hint: use FOIL) to identify the terms.
The x^2-term, or quadratic term, is
. The x-term, or linear term, is
. The number term, or constant term, is –20.

<h2>
The binomial is a factor of the polynomial.</h2>
Step-by-step explanation:
If a polynomial is divided by a binomial and the remainder is 0.
Then the binomial is a factor of the polynomial.
If a polynomial g(x) is divided by (x-a) ,it gives g(a) as remainder
Then g(x) = (x-a) Q(x) + g(a)
Hera g(a) = 0
So, g(x) = (x-a) Q(x)
It shows that (x-a) is a factor of g(x)
