Answer:
Step-by-step explanation:
a = - 4
b = 10
c = - 8
The discriminate is
D = b^2 - 4ac
D = 10^2 - 4*(-4)(-8)
D = 100 - 128
D = - 28 which is not a nice number
Because the Discriminate has a minus result, there are no real zeros.
Answer: the answers are the second one and the last one
x km : 7,735 m
kilometers : meters = 1 : 1,000
(1 meter) ÷ (1,000)
1 meter = 0.001 km
7,735 meters = 7.735
Correct Answer = A) 7.735 km
-k+0.03+1.01k=-2.45-1.8k
0.03-k=-2.45-2.81k
2.48=-3.81k
it wouldn't equal up so no solution
