Answer:

Step-by-step explanation:

x² + 13x + 36= 0

x² + 4x + 9x + (9*4)= 0

x*(x + 4) + 9*(x + 4) = 0

(x+4) (x +9) =0

x + 4 = 0      or  x + 9 = 0

  x = -4         ;            x = -9

postnew [5]

Answer:You have 30 days from the date of purchase to title and pay sales tax on your newly purchased vehicle. If you do not title the vehicle within 30 days, there is a title penalty of $25 on the 31st day after purchase. The penalty increases another $25 for every 30 days you are late with a maximum penalty of $200.

When you purchase your vehicle, you may obtain a temporary permit, transfer license plates from a vehicle you already own, or you may purchase new license plates. Our online sales tax calculator may help you estimate the taxes and fees you will pay.
