You should use the formula - b+-√b^2- 4 ac/2a. A=2 B=4 C=-3. Plug these numbers into the formula. If you get a negative in the square root try using a method called the box method.

\bf ~~~~~~ \textit{Compound Interest Earned Amount}

A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$1000\\
r=rate\to 3\%\to \frac{3}{100}\to &0.03\\
n=

\end{cases}
\\\\\\
A=1000\left(1+\frac{0.03}{1}\right)^{1\cdot 2}\implies A=1000(1.03)^2

is that enough to pay the $1100?


now, let's write 1000(1+r)² in standard form

1000( 1² + 2r + r²)

1000(1 + 2r + r²)

1000 + 2000r + 1000r²

1000r² + 2000r + 1000   <---- standard form.

I NEED ASAP:<br> What is the value of x?
Vitek1552 [10]

Answer:

x=48

Step-by-step explanation:

10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees

Get the variables together

10x-20+6x+8=180

-6x       -6x

4x-20+8=180

add together -20 and 8

4x-12=180

add -12 on each side

4x-12=180

   +12  +12

4x=192

divide all by 4

x=48
