On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles
rjkz [21]
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

Factor the quadratic expression 3x to the 2nd power +9x +6
Naily [24]

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)
