Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42

Answer:
Last Option moved
units right
Step-by-step explanation:
If we have a function f(x) and we want to move it horizontally then we make the transformation:

If
then the graph of f(x) moves horizontally h units to the right
If
then the graph of f(x) moves horizontally h units to the left.
In this case we have the function
and the transformation is performed to obtain 
Notice that in this transformation

<u><em>Then the graph of
moves horizontally
to the right</em></u>
Answer: SECOND OPTION
Step-by-step explanation:
The area of a parallelogram can be calculated with this formula:

Where "b" is the of one base and "h" is the height.
You can observe in the figure that "b" and "h" are:

Then, substituting these values into the formula, you get that the area of the given parallelogram is:

This matches with the second option.
To get 75 using 7, 5, 6, and 3 only once:
= (7+5) * 6 + 3
parentheses first
= 12 * 6 + 3
multiplication before addition
= 72 + 3
= 75
Without being given any constraints, I'm assuming multiplication and addition were allowed.
Hope this helps! :)
