Eghh I'm so bad at Algebra >.< Help? The length of a rectangle is 9.7 cm more than 4 times the width. If the perimeter of the rectangle is 91.4 cm, what are its dimensions? Or with this one? A rental car agency charges a flat fee of $110.00 plus $46.00 per day to rent a certain car. Another agency charges a fee of $70.00 plus $54.00 per day to rent the same car. Using a graphing calculator, find the number of days for which the costs are the same. Round your answer to the nearest whole day.

    hello you should get \[100=70+8x\] \[40=8x\] \[5=x\]

    I'm not sure why i wrote the formula for area in my picture. They actually give you the perimeter, do you know that formula? :)
