Answer:
x= -3+√2 or x= -3-√2 ( answer : A and B )
Step-by-step explanation:
hello :
x²+6x+9 = (x+3)².....identity
x²+6x+9 =2 means : (x+3)²=2
so : (x+3 = √2) or (x+3 = - √2)
so two solutions :
x= -3+√2 or x= -3-√2
6,051m = 6,000m + 51m
1km=1,000 metres
--------------------------------
Therefore:
6,051 metres = 6,000/1,000km + 51/1,000km
=6,051/1,000km
=6.051km
Answer:
