D. On any given workday after 4pm, the number of persons leaving an office building per minute is found to follow a geometric progression. The number of persons leaving in the sixth minute
is four times the number leaving in the eighth minute. Additionally, after four minutes a total
of 45 people left the office building. Determine the number of persons leaving the office
building in the first minute as well as the common ratio.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
