109x is the expression that could be used to determine the total number of cupcakes made given that a parent made x cupcakes for each of the 109 students in the fourth grade. This can be obtained by forming the algebraic expression for the given conditions.
<h3>Find the required expression:</h3>
- Algebraic expression is made up of numbers, operations and variables.
- Algebraic expression is true for all values of x.
- For example, 2x, 5x + 9 etc.
Given that,
A parent made x cupcakes for each of the 109 students in the fourth grade.
The total number of students in the class = 109
The number of cupcakes one student gets = 1 × x = x
⇒ The number of cupcakes 109 student gets = 109 × x = 109x
Hence 109x is the expression that could be used to determine the total number of cupcakes made given that a parent made x cupcakes for each of the 109 students in the fourth grade.

The answer is 8n^2
2x2 is 4 x 2 is 8 two n variables so multiple it by 2 and you get your answer
Given the table below which contains data from 200 endothemic reactions involving <span>sodium bicarbonate:
![\begin{tabular} {|c|c|} Final Temperature Conditions&Number of Reactions\\[1ex] 266 K&48\\ 271 K&60\\ 274 K&92 \end{tabular}](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%0A%7B%7Cc%7Cc%7C%7D%0AFinal%20Temperature%20Conditions%26Number%20of%20Reactions%5C%5C%5B1ex%5D%0A266%20K%2648%5C%5C%0A271%20K%2660%5C%5C%0A274%20K%2692%0A%5Cend%7Btabular%7D)
We find the probability distribution function as follows:
Let X denote the final temperature, then
