First distribute the 2x to get:
4x² + 10x
Then distribute the -5 to get:
-10x - 25
Then combine
4x² + 10x - 10x - 25
The 10x's will cancel leaving you:
4x² - 25
The surface area is ≈ 451.92

Step-by-step explanation:
Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.
Hence, the answer is $99.89.
So we know 20% of the audience are teenagers, and there are 360 teenagers.
Therefore, 1/5 of the audience members were teenagers, and that means 1/5 of the audience members is 360.
Multiply it by 5 to get answer:
360 * 5 = 1800
The total number of audience members are 1800.
