What is the constant terim in the expression 7k + 8 + 2lk + 3l? answer quick!

ehidna [41]

Answer:

The constant in the expression is '8'.

Step-by-step explanation:

The constant is a number with no variable multiplied with the constant.

In this expression, 7k has a variable 'k', which is not a constant.
If we look at 8, we can tell that it has no variable multiplied. This is a constant.
When we look at the 2lk and 3l, they both have variables 'lk' and 'l' respectively. They are not constants.

Hence, the constant in the expression is '8'.
