Answer:
-4x^3 +x^2+4x-3
Step-by-step explanation:
Answer:
first option
Step-by-step explanation:
If ( x + h) is a factor of f(x) then f(- h) = 0 , then
If (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 7 - 5(- 1)³ - 10(- 1)² + 2(- 1)
= 7(1) - 5(- 1) - 10(1) - 2
= 7 + 5 - 10 - 2
= 12 - 12
= 0
Since f(- 1) = 0 then (x + 1) is a factor of f(x)
Answer:
8 and 10
Step-by-step explanation:
All you need to know to begin setting this up is that to get from one even integer to the next consecutive even integer, add 2.
Start with x = an even integer (yes, because you say so!)
Next even integer = x + 2
"five times the first integer is equal to four times the second integer"
5x = 4(x + 2)
Distribute the 4.
5x = 4x + 8
Subtract 4x
x = 8
The two integers are 8 and 10
5(8) = 4(10) as desired!
Answer:
A
Step-by-step explanation:
112/0.8 = 140
Answer:
392
Step-by-step explanation:
28 times 14
or you can take 1 divided by 28 and you should get 0.03571428571428571 then take 14 times 0.3571428571428571 and you should get 39.2 and then just move your decimal place over to the right one place. and your answer will be 392 miles
