= 34.01
-760

Answer: b) the sum of six times a number and five
Step-by-step explanation:
The given expression is , where b represents any number.
The above expression has two terms combined by addition operation.
In the first term there is one variable b and 6 as coefficient of b and the second term is a constant term of 5.
Therefore, the correct description of the given expression is " the sum of six times a number and five".
