First you gotta distribute.
4 (1.75y - 3.5) + 1.25y
4 * 1.75 y = 7
4* (-3.5) = (-14)
7y - 14 + 1.25y
Combine like terms
8.25y - 14
The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.

Step-by-step explanation:
Answer:
Well my dude you have to show a picture or something for us to know
Step-by-step explanation:
= (8n² - 3n + 10) + (-3n² - 6n - 7)
= (8 - 3)n² + (-3 - 6)n + (10 - 7)
= 5n² - 9n + 3
Option → #1
