Answer:
B
Step-by-step explanation:
The transformation is proved through comparing the size of the bigger triangle to the smaller triangle in the individual sides. So the size of A F/ AB should be equal to AG / AC due to transformations making A F and AG the same times longer as AC and AB. By performing those calculations, you get 3.
18/38 - 47% chance of success
$1 to $100 - $10 to spend
With this given information, their is two routes to take, play it safe, or defy the odds. Though, a 47% chance isn’t far from 50/50, and at the end of the day, it is only $10 to lose. Therefore, in my opinion, even with the expected value, I would say to bet all the money at once, since the goal is to leave with $20.
Answer:
His inference is valid.
Step-by-step explanation:
The actual percentage of 12/13 is 92.31%, which rounds to 92%.

Answer:
x¹³ - x⁹ - 9x⁸ + 9x⁴
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ
Now, for the given:
To answer the question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final expression.
This can be done as follows:
(x⁸ - x⁴)(x⁵ - 9)
x⁸(x⁵) + x⁸(-9) - x⁴(x⁵) - x⁴(-9)
x¹³ - 9x⁸ - x⁹ + 9x⁴
Rearrange in order of decreasing powers, we will end up with:
x¹³ - x⁹ - 9x⁸ + 9x⁴
Hope this helps :)
