Which of the following is a fully factored expression of 24x – 56y + 72?
2 answers:
Answer:
Option C.
Step-by-step explanation:
The given expression is
We need to find the fully factored expression of given expression.
The given expression can be rewritten as
Now, it is clear that 8 is the GCF in all terms.
Taking GCF, we get
It is the fully factored form of the given expression.
Hence, the correct option is C.

Well, we know the cyclist left the western part going eastwards, at the same time the car left the eastern part going westwards
the distance between them is 476 miles, and they met 8.5hrs later
let's say after 8.5hrs, the cyclist has travelled "d" miles, whilst the car has travelled the slack, or 476-d, in the same 8.5hrs
we know the rate of the car is faster... so if the cyclist rate is say "r", then the car's rate is r+33.2
thus
solve for "r", to see how fast the cyclist was going
what about the car? well, the car's rate is r + 33.2
