An object falls 9 m in the first second, another 27 m in the second second, and then 108 m more in the third second. if this pattern continues, how far will the object fall during the first 4 seconds?

360 m

684 m

426 m

117 m

B) 684m

Step-by-step explanation:

From 9 to 27 is a 3 times increase, from 27 to 108 is a 4 times increase. So following the pattern, we can determine that it will increase 5 times, and fall another 540m in second 4. Then, we simply add all the numbers together to get the answer!

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
