Ratio=number of Km / number of hours
Data:
Number of Km=5 Km
Number of hours=1 1/2 hour=1.5 hour.
Ratio=5 km/1.5 hour=3.333... km/h≈3.33 km/h.
Answer; their ratio was 3.33 Km/h.

First simplify it so it would become -1 x^2 over 6 x^5
then you need to simplify the x's so do 5-3 so the final answer is -1 over 6 x^3
Set C. because every number has a 5 difference between each other.
Answer:
= 2x²( 2x+ 1) + 2x
or
= 2x (2x² + x + 1)
Step-by-step explanation:
Given in the question two functions,
f ( x ) = 9x³ + 2x² − 5x + 4
g ( x ) = 5x³ − 7 x + 4
To find,
f ( x ) − g ( x )
Substitute each functions
= 9x³ + 2x² − 5x + 4 - ( 5x³ − 7 x + 4 )
Remove parentheses
= 9x³ + 2x² − 5x + 4 - 5x³ + 7 x - 4
Combine like terms and add them up
= 4x³ + 2x² + 2x
Factorise
= 2x²( 2x+ 1) + 2x
or
= 2x (2x² + x + 1)
So the final answer in factored form is 2x²( 2x+ 1) + 2x or 2x (2x² + x + 1)
This can't be further factorise because answer will be in complex numbers
