We have the expression
![5x+2x](https://tex.z-dn.net/?f=5x%2B2x)
We have to convert the expression in a single-term expression. We apply the distributive property:
![5x+2x=(5+2)\cdot x=7x](https://tex.z-dn.net/?f=5x%2B2x%3D%285%2B2%29%5Ccdot%20x%3D7x)
b) We have to substitute five different values into the expressions 5x+2x and 7x-1.
The first expression is equal to 5x+2x=7x.
We then can predict that the difference between 7x and 7x-1 is 1.
For example, for x=2, we have 7x=7*2=14 and 7x-1=7*2-1=14-1=13.
We can calculate if the two expressions can be equal, we write:
![\begin{gathered} 5x+2x=7x=7x-1 \\ 7x=7x-1 \\ 7x-7x=-1 \\ 0=-1\longrightarrow\text{False} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%205x%2B2x%3D7x%3D7x-1%20%5C%5C%207x%3D7x-1%20%5C%5C%207x-7x%3D-1%20%5C%5C%200%3D-1%5Clongrightarrow%5Ctext%7BFalse%7D%20%5Cend%7Bgathered%7D)
There is no value that can make both expressions equal.
Both equations have a difference of 1 for any value of x.

Answer:
<h2>32,768 views</h2>
Step-by-step explanation:
Given the relationship between the elapsed time, tea, in days since the videos first uploaded, and the total number of views, V(d) that the video received modeled by the following function
V(d)=![4^{1.25d}](https://tex.z-dn.net/?f=4%5E%7B1.25d%7D)
In order to know the number of views the video will receive after 6 days, we will substitute the number of days i.e d = 6 into the modeled equation as shown;
![V(6)=4^{1.25(6)}\\V(6)=4^{7.5}\\V(6) = 32,768views](https://tex.z-dn.net/?f=V%286%29%3D4%5E%7B1.25%286%29%7D%5C%5CV%286%29%3D4%5E%7B7.5%7D%5C%5CV%286%29%20%3D%2032%2C768views)
Hello!
Here we have $21.28 total spent and paid for with $30. So 30-21.28= $8.72 so our change must equal this amount. The only choice then would be A.
Hope this helps. Any questions please ask. Thank you kindly.
Hey there!
2^2 + 5 + 50 ÷ 2(5)
2^2 = 2 • 2 = 4
4 + 5 + 50 ÷ 2(5)
4 + 5 = 9
9 + 50 ÷ 2(5)
50 ÷ 2 = 25
9 + 25(5)
25(5) = 125
9 + 125
= 134
Answer: 134 ☑️
Good luck on your assignment and enjoy your day!
