b)
so, 13 pages in 1/3 of an hour
for this we have to divide the time needed for the 13 pages by 13:

so each page requires

of an hour, which is approximately 1.5 minutes.
The expression can be simplified to a polynomial of degree 2.

<h3>
How to simplify the expression?</h3>
Here we have the expression:

We can directly simplify this by taking the variable as common factor:

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.
