Lena thinks of a number, x. she finds the sum of the number and 4. she squares the entire quantity, and then divided it by the product of 3 and the number. enter an algebraic expression that shows the operations she performed.

Step-by-step explanation:

Let the number that Lena thinks of is x.

Then she finds the sum of the number and 4 i.e. (x + 4).

Then she squared the entire quantity as (x + 4)².

Now, she divided the final term by the product of 3 and the number.

Here, the product of 3 and the number is 3x.

Therefore, ultimately Lena will get the algebraic expression as . (Answer)
