I'll just clarify the choices you gave:
-<span>maximum amount of money you can charge on the credit card time before the credit card company starts charging late fees
</span>-l<span>east amount of money that must be paid at the end of a month
</span>-<span>period of time before the credit card company starts charging interest
If these are correct, then the answer is 'period of time before the credit card company starts charging interest'. </span>
Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
( (r+2) * (2r-9)-(r^2+17r+30) )/(r+2)
none of the parenthetical operations or power operations can be simplified further, so multiplication and division first, left to right:
(2r(r+2) -9(r+2) - r^2 + 17r +30)/(r+2)
(2r^2 + 2r -9r+18 -r^2 +17r +30 )/(r+2)
(r^2 +10r +48)/(r+2)
The are you have selected
