To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:
Then group terms to simplify:
Simplify any like terms:
And group together again:
You can simplify a 3 out of the first expression one more time to get:
Which would be the factored form. I hope this helps :)
Answer:
I think it is probably the 2nd option
Step-by-step explanation:
I'm not entirely sure about the words theoretical and experimental.
I am guessing that experimental means the probability that they got in the table
And I think theoretical means what the mathematical probability should be.
As far as I can tell the theoreticall probability for each part of the pie is 33.33333....
Since each part is equal and there are 100 spins
using these definitions only option 2 makes sense
Time zones<span> and </span>time<span> offsets. A </span>time zone<span> is a geographical region in which residents observe the same standard </span>time<span>. A </span>time<span> offset is an amount of </span>time<span> subtracted from or added to Coordinated Universal </span>Time<span> (UTC) </span>time<span> to get the current civil </span>time<span>, whether it is standard </span>time<span> or daylight saving </span>time<span> (DST)
I hope my answer has come to your help. God bless you and have a nice day ahead!

Answer:
what do you need help with
Step-by-step explanation:
Let m the tens digit and n the ones
the Original number is 10m+n
7(m+n) =10m+n
7m+7n=10m+n
6n=3m
Reversing the number 10n+m
10n+m=18+n+m
9n=18
n=2
6n=3m
6(2)=3m
3m=12
m=4
the number is 10m+n=10(4)+2=42
