Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
Answer:
Yes, as far as we know from the data given
Step-by-step explanation:
A function will have a single output for each unique input. The output does not have to be unique for each unique input.
If we had an example where a single input resulted in two or more different outputs, then that is not a function.
By example if the next term were x = 6 and y = -4, then that example would make it not a function as 6 would map to both -4 and +5

Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
![k = \frac{Final\ Volume}{Initial\ Volume}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7BFinal%5C%20Volume%7D%7BInitial%5C%20Volume%7D)
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
![k = \frac{216\ cubic\ units}{8\ cubic\ units}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B216%5C%20cubic%5C%20units%7D%7B8%5C%20cubic%5C%20units%7D)
<u>k = 27</u>
<u></u>
b.
Final Volume = 1 cubic units
Therefore,
![k = \frac{216\ cubic\ units}{1\ cubic\ units}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B216%5C%20cubic%5C%20units%7D%7B1%5C%20cubic%5C%20units%7D)
<u>k = 216</u>
<u></u>
c.
Final Volume = 1000 cubic units
Therefore,
![k = \frac{216\ cubic\ units}{1000\ cubic\ units}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B216%5C%20cubic%5C%20units%7D%7B1000%5C%20cubic%5C%20units%7D)
<u>k = 0.216</u>
