Answer:

4a^2 + 12ab + 9b^2.

Step-by-step explanation:

Use the identity (a + b)(a + b) = a^2 + 2ab + b^2 :

(2a + 3b)(2a + 3b)

= (2a)^2 + 2*(2a)(3b) + (3b)^2

= 4a^2 + 12ab + 9b^2.

Liono4ka [1.6K]

Answer:

$\$487.48$

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 Final Investment Value

P is the Principal amount of money to be invested

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

$t=10\ years\\ A=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4$

substitute in the formula above

$1,000=P(1+\frac{0.0725}{4})^{4*10}$

$1,000=P(\frac{4.0725}{4})^{40}$

$P=1,000/(\frac{4.0725}{4})^{40}$

$P=\$487.48$
