Marshall deposited $3,300 in a savings account with simple interest. Six months later, the account held $3,415.50. What was the

15x^3+4x^2+14x+12 Multiply 3x by every value in the second bracket. Then multiply 2 by every value in the second bracket. Add like terms. (Only answers with the same square are like terms.)
