Can someone simplify -7(3e-2f+4)+6e-2 ? i need

-7(3e-2f+4)+6e-2
=-21e + 14f - 28 + 6e - 2
=-15e + 14f - 30

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?
