Answer:

-5cd

Step-by-step explanation:

-3cd - d(2c - 4) - 4d

To get simplified expression we use order of operation PEMDA

WE start with parenthesis. Distribute -d inside the parenthesis

-3cd - 2dc +4d - 4d

Now we combine like terms  that has same variables

4d-4d becomes 0

Expression becomes

-3cd - 2dc. Both terms has same variables  so we add it

-5cd

A cylinder shown below has a volume of 300 pi cubic inches. What is its height?
velikii [3]

The volume of a cylinder depends on both the cylinder's height and its radius.
There are an infinite number of different cylinders, all with different dimensions,
that all have 300π inches³ of volume. In order to calculate either dimension of
a cylinder, both the volume and the other dimension must be known.

We sense a high probability that the picture described as "shown below"
tells the cylinder's radius.  Sadly, we have not been made privy to that
bit of information, leaving us out in the cold with no way to calculate the
cylinder's height.

Find the values of x, y, and z for which ABCD must be a parallelogram.
Rudik [331]

Answer:

A. x = 50, y = 130, z = 130

Step-by-step explanation:

50 and z are adjacent angles,

Sum of adjacent angles = 180,

50 + z = 180

z = 180 - 50

z = 130

z and x are adjacent angles,

Sum of adjacent angles = 180,

x + z = 180

130 + x = 180

x = 180 - 130

x = 50

z and y are opposite angles,

Opposite angles are equal in a parallelogram,

z = y = 130
