Cody made deposits of $45, $18, and $27 into his checking account. He then wrote checks for $21 and $93. What would the expression look like if you used integer addition?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
