Answer:
B
Step-by-step explanation:
Its hard to explain. Hmm lets see...okay so -1/4 is a quarter of -1 also -25%. so lets think of -1 to be -100% makes sense? and its opposite is mirrored on the number line. Hope that helped
Selections 2, 3, 5, 6 are polynomials.
1 and 4 are not. The coefficients don't have to be integers, but the powers of the variables need to be positive integers. In 1, you have x^-1. in 4, you have x^(1/2).
You would first put 168 over 4 and simplify to get 42 over 1. Then you would divide 504 by 42 to get 12. You would have to drive 12 hours to get 504 miles.
