First you do -3bk+9bk and that equals 6bk then since there are no more like terms the experssion would be simplified into 6bk+2-6b
HOPE THAT HELPED!
Answer:
you can do 2^12=4096
there are 4096 different ways nick can answer the question
(15a^4 - 30a^5 )/5a^2
= 5a^2(3a^2 - 6a^3) / 5a^2
= 3a^2 - 6a^3
or
= - 6a^3 + 3a^2
The mode is the number that shows up the most.
In the dataset, note that the stem should be in the tens place, and the different number of leaves are in the ones place.
62 shows up one more time than all the other numbers, and so 62 is your answer.
Hope this helps
