The simplification of the polynomial expression will give 3x² - 20x + 8.
<h3>How to illustrate the polynomial?</h3>
The polynomial expression is given as:
(5x² + 13x4) (17x² + 7x - 19) + (5x-7)(3x + 1)
= 5x² + 13x - 4 - 17x² - 7x + 19 + 15x² + 5x - 21x - 7
Then collect like terms
= 5x² + 15x² - 17x² + (13x - 7x + 5x - 21x) - 4 - 7 + 19
= 3x² - 20x + 8.

Answer:
4.4 cm
Step-by-step explanation:
To solve this problem, we have to remind the conversion factor between feet and cm. We know that:
1 foot = 12 inches
1 inches = 2.54 cm
So,

In this problem, Sarah's height right now is
h = 148 cm
She wants to be 5 feet tall by her next birthday: it means that her height should be

Therefore, she needs to grow by:

So, she needs to grow 4.4 cm more in order to be 5 feet tall.
