Pamela's bank account showed -$120 on friday. if there were 5 transactions that occurred in her bank account, what was the mean (average) amount of each transaction? show your work.

-24

Step-by-step explanation:

If there were 5 transactions, 5 times the mean amount of the transactions will add up -120. If "x" is the mean amount of the transactions:

5*x = -120

x = -120/5

x = -24

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
