The correct answer is as follows

  • Part A : 3x+4
  • Part B : 2 times the sum of a number and 9.

What is algebraic expression?

  • It is a mathematical expression that consists of variables, numbers and operations.

How to solve the Problem?

  • To solve the problem the steps are as followed

For Part A

  • We need to write an algebraic expression

Let us assume the number to be x

Then 3 times a number is 3*x = 3x

Now as per statement 4 more than 3 times a number describes

adding 4 to 3 times a number that is 3x+4

Hence the algebraic expression is 3x+4

For Part B

  • We need to write a verbal expression for 2(n + 9).

Now as per the statement given we can say that n is a number

and n+9 is sum of a number and 9

Therefore ,

2(n+9) can be described as 2 times the sum of a number and 9
