Answer:45.5
Step-by-step explanation:convert mixed number into proper fraction
6.2+1/2=13/2
=7x 13/2
covert element to fraction 7= 7/1
7/1x13/2=91/2
answer:45 1/2
there's also a decimal answer
answer:45.5
I believe its B because it matched the y intercept of the question as you can see by the picture I put.
So what do u need help on??
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.
