Einstein Office Equipment has a rental plan for office machines. A fax machine that lists for $722.98 can be rented for 22% of t
Archy [21]

Answer:

$13.68


Step-by-step explanation:

Assuming they rent for 1 year, the cost is broken down as follows:


Annual renting cost = 22% of 722.98 = \frac{22}{100}*722.98=0.22*722.98=159.06


Usage charge = 3.2% of 159.06 = \frac{3.2}{100}*159.06=0.032*159.06=5.09

Thus,

Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15


Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):

\frac{164.15}{12}=13.68 dollars

Find the area of the shaded region in the image below. Write your answer as a simplified polynomial in standard form.
Misha Larkins [42]

Answer:

6x^2+17x+9

Step-by-step explanation:

you have to subtract the area of the white rectangle from the area of the entire rectangle

to find the area of the inner rectangle do (2x-3)*(x+1)=2x^2-3x+2x-3=2x^2-x-3

to find the area of the entire rectangle do (4x+6)*(2x+1)=8x^2+12x+4x+6=8x^2+16x+6

(8x^2+16x+6)-(2x^2-x-3)=8x^2+16x+6-2x^2+x+3=6x^2+17x+9
