Oh I think is because when u write or draw a number line u write like 1,2,3,4,5 ... and -1,-2,-3... and so when u write point something....and so u have 0.6 and 0.25 and 0.6 is greater because it came first 0.6 came before 0.25
Ok so R=alfonso's rate
w=wind rate=4
d=rt
with wind rate is R+4
agaoins wind rate is R-4
with wind distance is 34
against is 18 miles
time is same
34=(r+4)t
18=(r-4)t
34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t
18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t
18/(r-4)=t
34/(r+4)=t
set equal to each other
18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph
answer is 13mph with no wind

Answer:
3(x + 1)(x + 2)
Step-by-step explanation:
Given
3x² + 9x + 6 ← factor out 3 from each term
= 3(x² + 3x + 2) ← factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are + 1 and + 2, since
2 × 1 = 2 and 2 + 1 = 3, thus
x² + 3x + 2 = (x + 1)(x + 2) and
3x² + 9x + 6 = 3(x + 1)(x + 2)
