A car is 500 feet behind a train. The train is traveling at a constant speed of 44 feet per second. If the car's speed could be modeled by the equation s(t)=4t^2, How long will it take for the car to catch up to the train. How many feet did the car travel before it caught up to the train?

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
