Michael earns 42 dollars per week working part-time at a book store. He makes one dollar more for each book that he sells. The amount, A (in dollars), that Michael earns in a week if he sells b books is given by the following.
A=42+ b

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

deez nut

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
