16k^2 + 16k + 4
We can first start off by dividing every term by 4:
4 (4k^2 + 4k + 1)
to factor, you find which two number you can multiply with each other to get the middle term. So 2 and 2 to get 4. Substitute that into the equation
4 (4k^2 + 2k + 2k + 1)
the first two terms become a group and the last 2 terms become a group. Factor like terms out of the two groups.
4 (2k (2k + 1) + 1 (2k + 1))
4 (2k + 1)(2k + 1)
Answer:
A: 6.8 is greater than 6.6
Answer:
$57,369
Step-by-step explanation:
We have been given that an amount of $53,000 is placed in an investment account that grows at a fixed rate of 2% (compound growth) per year. We are asked to find the amount in the account after 4 years.
To solve our given problem we will use compound interest formula.\
, where,
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
Let us convert our given rate in decimal form.

Upon substituting our given values in compound interest formula we will get,





Therefore, an amount of $57,369 will be in the account after 4 years.
