Agarden has the shape of a right triangle with one leg 6 meters longer than the other. the hypotenuse is 6 meters less than twice the length of the shorter leg. what is the length of the shorter leg?

Leg one: x (shorter side)
Leg two: x+6
Hypotenuse: 2x-6
Use a^2+b^2=c^2
x^2+(x+6)^2=(2x-6)^2
x^2+x^2+12x+36=4x^2-24x+36
2x^2+12x=4x^2-24x
36x=2x^2
36 = 2x
x = 18

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.
