Answer:
18(p-2)
Step-by-step explanation:
We want to factor 
We know that the greatest common factor is 18.
So we can rewrite to obtain:

We factor the GCF to obtain:

Therefore 
Therefore the equivalent expression to 18p-36 is 18(p-2)
The zeros are 3 and -5. Hope this helps!
His equation could be written in quadratic form, which is ax^2+bx=c
For the answer to the question above, we'll have to use the formula for velocity which is v =<u> d
</u> t and d = vt
Since the total distance is given, therefore we can get the time and it will look like this.
220t + 250t = 1880
<u>470t</u> = <u>1880
</u>470 470
the problem indicates that the train runs 250kph
Let's substitute:
d = 250(4)
the distance traveled by Lian is 1000km
