Answer:

D

Step-by-step explanation:

x^2 - 7x + 12 +  (x - 3)^2             Add (x - 3)^2 after it has been expanded.

x^2 - 7x + 12 + x^2 - 6x + 9        Combine like terms

2x^2 -7x - 6x + 21

2x^2 - 13x + 21                           Factor

(2x - 7)(x - 3)

Which is exactly what D says.

so r=126/3 = 42 miles/hr

d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
