Answer:

k = 9

Step-by-step explanation:

For this, we can factor the top expression to look like the bottom expression.

So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.

18[tex]x^{2}[/tex]            11x

1 and 18       19   - No

2 and 9       11    - Yes

3 and 6       9    - No

So, the numbers are 2 and 9. The expression should now look like this:

[tex]x^{2}[/tex] + 2x + 9x + 18

Now, undistribute the terms.

x(x + 2) + 9(x + 2)

(x+2)(x+9)

This matches up with the bottom expression.

The value of k is 9.

Veronica takes of an hour to write of a page of calligraphy.

Answers

Using proportions, it is found that it will take Veronica 4/3 of an hour to write one page of calligraphy.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, it is found that she takes 1/3 of an hour to write 1/4 of a page of calligraphy. How long it takes her to write a page?

The rule of three is:

1/3 hour - 1/4 page

x hours - 1 page

Applying cross multiplication:

[tex]\frac{x}{4} = \frac{1}{3}[/tex]

[tex]x = \frac{4}{3}[/tex]
