Which algebraic expression is a polynomial with a degree of 5?3x5 + 8x4y2 – 9x3y3 – 6y52xy4 + 4x2y3 – 6x3y2 – 7x48y6 + y5 – 5xy3 + 7x2y2 – x3y – 6x4–6xy5 + 5x2y3 – x3y2 + 2x2y3 – 3xy5

Answer:2xy4 + 4x2y3 – 6x3y2 – 7x4Step-by-step explanation:The degree of a polynomial is the highest exponent of the expression. If there is more than one variable, the degree is calculated by adding the the exponents of the variables in the term.3x5 + 8x4y2 – 9x3y3 – 6y5  has the term x3y3 and x4y2 which is degree 62xy4 + 4x2y3 – 6x3y2 – 7x4  has the term x2y3 and x3y2 which is degree 58y6 + y5 – 5xy3 + 7x2y2 – x3y – 6x4  has the term y6 which is degree 6–6xy5 + 5x2y3 – x3y2 + 2x2y3 – 3xy5 has the term xy5 which is degree 6
