The sum of the polynomials 2n³ + 4n² - 7 and -n³ + 8n - 2 will be n³ + 4n² + 8n - 9. Then the correct option is B.
<h3>What is polynomial?</h3>
A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
The polynomials are given below.
2n³ + 4n² - 7 and -n³ - 8n - 2
The sum of the polynomials will be
⇒ 2n³ + 4n² - 7 + (-n³ - 8n - 2)
⇒ 2n³ + 4n² - 7 - n³ - 8n - 2
⇒ n³ + 4n² - 8n - 9
The sum of the polynomials 2n³ + 4n² - 7 and -n³ + 8n - 2 will be n³ + 4n² - 8n - 9.
Then the correct option is B.

Answer:
y = 6
x = 200
Quick Explanation:
The horizontal arrowed line labeled <em>t</em> would be the <em>y </em>axis, and according to the dot on the graph, it's on the 6. The vertical arrowed line labeled <em>h </em>would be the <em>x </em>axis, and the dot tells you the number is 200. Easy peasy, just remember the <em>x </em>axis is vertical and the <em>y</em> axis is horizontal and it'll help you find the location of any dot.
Answer:
Step-by-step explanation:
<u>Let's simplify this further to get our answer.</u>
- -5/6(12 - 6x + 18y)
- => -60/6 + 30x/6 - 90y/6
- => -10 + 5x - 15y
Looking at the options, we can say that Option C and B are correct.
The two events are related and often or always follow each other
