A children's wind-up car toy travels a distance, d inch- es, as modeled by the function d = 12 +8t where t is
the number of seconds after the car has been wound
up and released. If the car is released at 12 feet, to
the nearest second, how many seconds would it take to
reach 21 feet?

Looks pretty good to me!

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
