Which is the product of (1 +41+3x) (2 - 7x–9x)?
1 answer:
Answer:
-48x^2 -666x+84
Step-by-step explanation:
Exponet is ^2.
Multiply is •
Use Distributed Property. Multiply the second parathesis by each term from the first parathesis.
Any expression multiplied by 1 remains the same. Distribute 41 through the parathesis. 41(2-7x-9x).
Distribute 3x through the parathesis 3x • (2-7x-9x).
You will have these numbers left: (Slide 2)
Add the numbers, 2 and 82 to get 84. Add -7x -9x + -287x -369x + 6x to get -666x. Add -21x^2 - 27x^2 to get 48x^2.
Use the communitative property to reorder the terms. And then your answer is -48x^2 -666x+84.

Answer: $ 55
Step-by-step explanation:
When interest is compounded continuously, the final amount will be
When interest is compounded daily, the final amount will be
, where P= Principal , r = rate of interest , t = time
For Hunter , P= $750, r =
t = 18 years
For London , P= $750, r =
t = 18 years
Difference = $ 2471.48 - $ 2416.24 =$ 55.24≈$ 55
Hence, Hunter would have $ 55 more than London in his account .
