I think it’s A, B, C or D
If x = -b/2a, then 2a = -b / x so a = -b / 2x or a = b / -2x
So the denominator is -2x because it has to take the minus sign that the numerator refused to take ;-)
Answer:0.357 meters is the answer hope this help give me a brainest please
Inequality:
(3/10) ≥ k - (3/5)
Add 3/5 to both sides:
k ≤ (3/10) + (3/5)
Use LCD:
k ≤ (3/10) + (6/10)
Combine:
k ≤ 9/10
