Add (1.3t^3 + 0.4t^2 -24t) + (18t + 0.6t^2) for each term in the second polynomial, enter the letter showing where that term should be placed to add the polynomials vertically =0.6t^2 = 0t^3 = 8 = -18t

To solve this problem you must apply the proccedure shown below:
 1- You have the following sum of two polynomials given in the problem above:
 (1.3t^3 + 0.4t^2 -24t) + (18t + 0.6t^2)
 2- When you add the polynomials vertically, you must order each term of the second polynomial under the terms of the first polynomial with equal exponent.
 The answer is:
 B=0.6t^2
 A=0t^3
 D=8
 C=-18t

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
