48-2x=96--------- -2x=48--------- x=-24. You multiply everything by 6 then solve.
Step-by-step explanation:
ax2 + bx + c = 0
x12 = (-b ± √D) / 2a , D = b2 - 4ac .
5x2 + 7x + 3 = 0
a = 5 , b = 7 , c = 3
D = 49 - 60 = - 11 , x1 = (-7 - i √11) / 10
x2 = (-7 + i √11) / 10
The answer is D. 15+18+12+5= 50 and there are 5 ramblers
