Answer:
x = 4 or x = -1
Step-by-step explanation:
2x^2 - 8x + 6 =0
divide by 2 we get : x^2 -4x +3 = 0
(x -4) (x+1)
x = 4 or x = -1
x(3.4+4.6+2.2)
x(10.2)
Each hiker will carry 10.2 lbs
if there are x hikers they will carry 10.2*x lbs
Umm, since x is -3 (given), your answer should be B, since B is the only one with -3 as an x
hope this helps
