(2x^2-4x-3)(3x+1)
Expand
(2x^2+−4x+−3)(3x+1)
Cross multiply
(2x2)(3x)+(2x^2)(1)+(−4x)(3x)+(−4x)(1)+(−3)(3x)+(−3)(1)
Simplify6x^3+2x^2−12x^2−4x−9x−3
Simplify6x^3−10x^2−13x−3 is your answer

$\qquad \textit{Compound Interest Earned Amount}\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad 
\begin{cases}
A=\textit{current amount}\\
P=\textit{original amount deposited}\to &\$3,500\\
r=rate\to 8\%\to \frac{8}{100}\to &0.08\\
n=\textit{times it compounds per year}\to &1\\

A=3500\left(1+\frac{0.08}{1}\right)^{1\cdot 2}\implies 3500(1.08^2)$

A boat traveled 27 miles in 2 hrs. At this rate, How many miles will the boat travele in 1/2 hrs

Mashcka [7]

Answer:

In explanation down below.

Step-by-step explanation:

So if the boat was able to travel 27 miles in 2 hours that means that it traveled 13.5 miles an hour. I think that you want to know how many miles the boat will travel in 1/2 an hour. Which is 6.75.

1 hour: 13.5 miles

1/2 hour the boat has traveled 6.75 miles.

I hope this helps!!!
