Let's call n the number of days Marika's been training for the race, and
the distance she runs on the nth day in meters. After the first day, when n = 1, she runs 100 meters, so

On the second day, she runs an additional 4 meters, on the third day, another 4, and so on. Here's what that looks like mathematically:

It would be easier to write this continued addition as multiplication, in which case those same equations would look like

Notice that, in every case, the number 4 is being multiplied by is 1 less than n. We could even write for our first term that
. In general, we can say that

Which is expressed by option B.

Step-by-step explanation:
area=6992m2
length=92m
Now,
area of rectangle=6992
Answer:
2
Step-by-step explanation:
(4)(−2)+10
=−8+10
=2
Johnny now has 90 so Jeana did not take 25 she only took 10
