Step-by-step explanation:
For the Cuboid, the formula will be:
Width x Height x Length
For the cylinder the volume formula will be:

X = 1 or any thing really it depends on the way you look at it
1. Since -4 doesn’t equal -2, we will use the first function. All you have to do is plug in -4 to x, and you should get
-3
2. -2=-2, so we will use the second function to get the answer of
3
3. Once again we will be using the first function, so just plug 5 into the answer to get
-7.5
Hope this helped :)
Answer: 3n-6
Step-by-step explanation: You have to use the distributive property. 3 times n is 3n and 3 times -2 is -6.
