The correct option is (B): (3x+2)(3x+1)

Explanation:
Add all the boxes:
9x^2 (boxes)
9x (boxes)
The constants = 2

So it becomes:
9x^2 + 9x + 2
9x^2 + 6x + 3x + 2
3x(3x+2) + 1(3x+2)

(3x+2)(3x+1)

$2000 was borrowed for 4 years with an interest rate of 3% compounded annually. What is the total amount owed at the end of the

kompoz [17]

Answer:

$\$2,251.02$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the total amount owed

P is the amount of money borrowed

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=4\ years\\ P=\$2,000\\ r=3\%=3/100=0.03\\n=1$

substitute in the formula above

$A=2,000*(1+\frac{0.03}{1})^{1*4}$

$A=2,000*(1.03)^{4}$

$A=\$2,251.02$
