It is (4*5)+(4*6) because if you do 4x6 it equals 20 then if you do 4x6 it equals 24 :)
I believe the answer is the last one. I hope this helps love! :)
Answer:
.
Step-by-step explanation:
Note: The given function is not correct.
Consider the given polynomial is

It is given that (x+1) is a factor of given function.
Using synthetic division, divide P(x) by (x+1) as shown below.
-1 | 1 0 -7 -6
| -1 1 6
--------------------------------------
1 -1 -6 0
--------------------------------------
Bottom line represents the coefficients of quotient except the last element because it is remainder. So, the given function can be written as




Therefore, the function as a product of linear functions is
.
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph
