One day susan's mom gave her a bag of candy. three days later she had 28 pieces of candy. eight days after her mom gave her the candy, she had 13 pieces of candy. if she ate the same number of candies each day, how many pieces of candy were in the bag originally.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

b). 4320 have a nice day

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
