Answer:
-35x + 21w + 7
Step-by-step explanation:
Basically all you have to do is multiply the -7 by all of the values inside of the parenthesis. The subtraction sign in front of the 3w and 1 made them negative numbers, when you multiple two negative numbers they become positive.
Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
![V = s^3](https://tex.z-dn.net/?f=V%20%3D%20s%5E3)
We can take the cube root of both sides:
![\sqrt[3]{V} = \sqrt[3]{s^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BV%7D%20%20%3D%20%5Csqrt%5B3%5D%7Bs%5E3%7D)
Just flipping it:
![\sqrt[3]{s^3}=\sqrt[3]{V}\\s = \sqrt[3]{V}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bs%5E3%7D%3D%5Csqrt%5B3%5D%7BV%7D%5C%5Cs%20%3D%20%5Csqrt%5B3%5D%7BV%7D)
We know our volume is 64 cubic feet. Let's put that into our equation as V:
![s=\sqrt[3]{64}](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B64%7D)
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
![s=4](https://tex.z-dn.net/?f=s%3D4)
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
![A = s^2](https://tex.z-dn.net/?f=A%20%3D%20s%5E2)
Since we know s, we can easily find the area A by squaring it:
![A = 4^2 = 16](https://tex.z-dn.net/?f=A%20%3D%204%5E2%20%3D%2016)
