the top and bottom margins of a poster are each 9 cm and the side margins are each 6 cm. the area of printed material on the poster is fixed at 864 cm2. find the dimensions of the printed area that minimize the area of the whole poster.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
