A rental car company charges an upfront fee to rent a car, and then charges $0.40 per mile driven. Suppose you rent a car from this company. Let (n) represent the varying number of miles that you drive in the car, and let (c) represent the total cost (in dollars) you will have to pay for the rental car. a. The number of miles driven, n, and the total cost of renting the car, c, are related by a constant rate of change.
What is this constant rate of change?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
