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.

to find the perimeter of the rectangle this is the expression:
x-9+x-9+3x-4+3x-4=138
if we simplify it:
8x-26=138
remember, 138 is what it all adds up to
the length is 11.5cm
the width is 57.5cm
the area is 661.25cm^2
the answers might not be correct use at own risk

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3
then the equation is (x-x₁)(x-x₂) = 0
if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.
