Amap of a highway has a scale of 2 inches = 45 miles. the length of the highway is 8 inches. there are 17 rest stops including one at each end. a new map is made with 1 inch = 30 miles. how far apart are the stops?

answer is equal to 8/2X45/30that is equal to6

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
