Answer:

17,37

Step-by-step explanation:

one number = x

The positive number = 2x + 3

x * (2x+3) = 629

x*2x + x *3 = 629

2x² + 3x - 629 = 0

2x² - 34x + 37x - 17*37 =0

2x*(x -17) + 37(x - 17) = 0

(x - 17)(2x + 37) = 0

x - 17 = 0 ; Ignore 2x + 37 as s is a positive number

x = 17

Positive number = 2*17 +3 = 34+3 = 37

Well you do 57 time 7 and get 399 and then it says how far will she have driven so you would add the 60 and get 459 miles.
