<em>The area of the rectangle is</em> $A=12b^6+6b^3-18b^2$

Step-by-step explanation:

<u>Area of a rectangle</u>

A rectangle of height H and width W has an area of:

$A=H*W$

The rectangle shown in the figure has a height of:

$H=3b^2$

And a width of

$W=4b^4+2b-6$

The area is

$A=(3b^2)(4b^4+2b-6)$

Operating:

$A=(3b^2)*4b^4+(3b^2)*2b-(3b^2)6$

$A=12b^6+6b^3-18b^2$

The area of the rectangle is $A=12b^6+6b^3-18b^2$

Answer:

28

Step-by-step explanation:

So in order to get this answer you want to use the combination formula which is $\frac{n!}{(n-r)!r!}$

Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation

so your going to have something looking like this $\frac{8!}{(8-2)!2!}$ now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.

hope this somewhat helps.

The original cost of Sam’s investment is $10,000. After liquidating the investment, Sam calculated his real return to be $10,700

OverLord2011 [107]

Answer:

Return on investment (ROI) = 7%

Step-by-step explanation:

Given:

Amount invested = $10,000

Total amount get (refund) = $10,700

Find:

Return on investment (ROI) = ?

Computation:

Amount Return = Total amount get (refund) - Amount invested

Amount Return = $10,700 - $10,000

Amount Return = $700

$Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7$

Return on investment (ROI) = 7%
