Answer:

$x^2+8x+12$

Step-by-step explanation:

The area of a rectangle formula is length times width.

The length of this rectangle is $(x+2)$ , and the width of this rectangle is $(x+6)$

Thus, the area of the rectangle is $(x+6)(x+2)$ . This can be expanded using FOIL.

First $x(x)=x^2$

Outer $x(2)=2x$

Inner $6(x)=6x$

Last $6(2)=12$

The two x terms combine, making 8x, and the answer is $x^2+8x+12$

To find the answer, set up an equation:
$\frac{45 \: miles}{1 \: hour} \times \frac{1000 \: meters}{1 \: mile} \times \frac{1 \: hour}{3600 \: seconds} =$
Using this set up we can cross out the units that are on opposite sides of the proportion such as miles and hours, leaving us with the desired units of meters and seconds. Then calculate m/s by multiplying 45 by 1000 meters and then dividing that value by 3600 seconds.

The resulting answer is 45mph = 12.5 m/s

If 0.5% of a number is 250, find the number

kaheart [24]

0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.

$\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000$
