Question

Which number is a constant in the algebraic expression?

Answer 1

Answer:

7

Step-by-step explanation:

The given algebraic expression is;

$-x^2-6y+13x+7$

This is an algebraic expression in x and y.

Any term that is independent  of these two variables is called the constant term.

The term '7' is independent  of these variables.

Hence the constant term is 7.
