1. Write an expression that looks like Sarah's expression: 5(2j + 3 + j). Replace the
coefficients so that your expression is not equivalent. You may use any number that you
choose to replace the coefficients. Be sure to leave the variables the same. For example,
8(3) + 7 + 3)) looks like Sarah's expression but is not equivalent.
