i need with the following question.
it is about math of finance.
questions:
a $3500 loan was settled ten years later with a payment of $8100. determine the annual rate of return.

The annual rate of return is 13.14%.

Step-by-step explanation:

As it is not mentioned whether the amount was compounded, so we will assume this to be simple interest.

Given is - A $3500 loan was settled ten years later with a payment of $8100.

Means total amount paid back was = $8100

And original principle was = $3500

So, interest paid = dollars

Now simple interest formula is :

Where p = 3500

I = 4600

r = ?

t = 10

Now putting these values in formula we get;

r=  0.1314

So, rate of interest = 13.14%

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
