Answer:
x = -12 x = -5
Step-by-step explanation:
-7x-60=x^2+10x
Add 7x to each side
-60=x^2+10x+7x
-60=x^2+17x
Add 60 to each side
0 = x^2+17x+60
Factor
What 2 numbers multiply to 60 and add to 17
12*5 = 60
12+5 = 17
0 = (x+12) (x+5)
Using the zero product property
x+12 = 0 x+5 =0
x = -12 x = -5
2 divided by 18 will equal 9
so just multiply that by the minutes (3)
9×3=27 minutes
