D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
For this case we must represent the following expression algebraically:
"eight more than the product of a number and two"
Let "x" be the variable that represents the unknown number
We have to:
the product of a number and two is represented as: 
Then, the full expression will be:

Thus, we use multiplication and addition.

Option C
Answer:
I don't want to do the problem for you but
Step-by-step explanation:
First you have to divide the figure into 2 parts. Then, you find the area of both the rectangles. You will also have to subtract the 8 from 12 which is 4 and after that you can subtract 5 from 18 because in a rectangle the opposite sides are the same. After you do those step you find the area of the rectangles.
Formula: Area= base * height
After you have to add both of the area up.
And that it!!
