Step-by-step explanation: This is actually very simple. Al you have to do is to find the area of the 3 rectangles, which adds up to be 96, and find the area of the triangles, which adds up to be 14. You then have to add 96 and 14, which results in 110.

$2(n + 5) = - 2$

Divide sides by 2

$\frac{2(n + 5)}{2} = - \frac{2}{2} \\$

$n + 5 = - 1$

Subtract sides 5

$n + 5 - 5 = - 1 - 5$

$n = - 6$

Done...

Two banks offer compound intereston your investment while you deposit with them. Bank A calculates compound interest annuallyand

Answer:

Bank B because the more often you compound interest, the more interest you earn.

Step-by-step explanation:

Bank A compounds the interest once a year.

Bank B compounds the interest twice a year.

Let's create an example of two investments of the same amount of money, the same interest rate, and the same time. The only difference will be the number of times the interest is compounded per year.

Compound interest formula:

$A = P(1 + \dfrac{r}{n})^{nt}$

where

A = future value

P = principal invested

r = interest rate

t = number of years

n = number of times interested is compounded in 1 year

Example:

P = $1000

r = 5%

t = 5 years

Bank A: n = 1

Bank B: n = 2

Bank A:

$A = $1000(1 + \dfrac{0.05}{1})^{1 \times 5} = $1276.28$

Bank B:

$A = $1000(1 + \dfrac{0.05}{2})^{2 \times 5} = $1280.08$

Bank A's investment is worth $1276.28 after 5 years, but Bank B's investment is worth $1280.08 after the same 5 years. Compounding twice per year instead of only once per year earns more interest.
