Answer:
-85/139
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-84)/(69-(-70))
m=-85/(69+70)
m=-85/139
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:
Step-by-step explanation:
58+q=180 (opposite angles of a cyclic quadrilateral are supplementary)
q=180-58=122°
similarly p+90=180
p=180-90=90°
Answer:It wants you to find the different angles and i suppose find x and plug it in
