-3z - (-z - 2)
In order to find the expression equivalent to our given expression, we have to simplify our given expression :)
-3z + z + 2
**Remember : the "z" and "2" become a positive because a negative times a negative is always a positive!**
Now, add like terms.
(-3z + z) + 2
Simplify.
-2z + 2
Look at our given answer choices.
Our answer is c. -2z + 2
~Hope I helped!~

Given: A cuboid with the dimesion below:
To Determine: The surface area of the cuboid
The formula for finding the surface area of a cuboid is given as:
From the diagram, it can be seen that
Substitute the given into the formula as shown below:
Hence, the surface area of the given cuboid is 130cm²
Answer:
you can find the height of a rectangular prism
6(x^2-1)(6x-1/6(x+1))
On factoring (x^2-1)=(x+1)(x-1)
= 6(x-1)(x+1)(6x-1/6(x+1))
Cancelling (x+1) from numerator and denominator we get,
= 6(x-1)(6x-1)/6
Cancelling 6 we get,
= (x-1)(6x-1)
