Algebraic expressions are expressions like:
[tex]3x^5+8x^2y^3+xy+8[/tex], [tex]x^2+2xy+y^3[/tex], [tex]a^3b+a^b+2ab-4[/tex],
so they are expressions made from integers, integers multiplying variables of different degrees, and algebraic operations like addition, subtraction etc...
thus, the algebraic expression for the product of 9 and a number t is 9t.
Answer: 9t
