Answer:
<u>27 cm²</u>
Step-by-step explanation:
Shaded Area = Area ABCE - Area AED
- S.A. = 6 x 6 - 1/2 x 3 x 6 [DE = 1/2AB = 1/2 X 6 = 3]
- S.A. = 36 - 9
- S.A. = <u>27 cm²</u>
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.
