Joe receives am average of 780 emails in his personal account and 760 emails in his work account each month. after changing his addresses, the number of emails in his personal account decreased by 10% and the number of emails in his work account decreased to 722 each month. how can joe calculate the number of emails he will receive each month in his personal account after changing his address?

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
