Checking for each option
Option A:

Substitute w = 10 and check if we'd get 900 as the answer

Option B:

Substitute w = 10 and check if we'd get 900 as the answer

Option C:

Substitute w = 10 and check if we'd get 900 as the answer

Option D:

Substitue w = 10 and check if we'd get 900 as the answer

Answer: Option B
The third one just like the previous question
Answer:
B
Step-by-step explanation:
the product (2x² - 3x - 8)(3x² + 5x + 1) is required
multiply each term in the second factor by each term in the first factor.
= 2x²(3x² + 5x + 1) - 3x(3x² + 5x + 1) - 8(3x² + 5x + 1) ← distribute
= 6
+ 10x³ + 2x² - 9x³ - 15x² - 3x - 24x² - 40x - 8
collecting like terms gives
6
+ x³ - 37x² - 43x - 8 → B
The answer is 0.40 or 0.4
