Answer:
To simplify the following expression: 6 / (7+3i), we're going to multiply and divide the entire expression by (7+3i), as follows:

Now, the denominator has NO imaginary numbers.
Answer:
See explanation below.
The selection of drop down arrows from top to bottom should be:
5; 4; 1; 2; 3
Step-by-step explanation:
Quadrilateral with exactly ONE set of parallel sides: Trapezoid (option 5)
Parallelogram with 4 congruent (equal) sides and 4 right angles: square (option 4)
Quadrilateral with 2 pairs of parallel sides (notice no reference to angles between sides and constrain about similarity in side length - so this os the most general description): parallelogram (option 1)
Parallelogram with 4 right angles (notice no constrain about the length of the sides): rectangle (option 2)
Parallelogram with 4 congruent sides (notice there is no constrain about the angles between the sides): rhombus (option 3)
To find the length of the room you will have to add up all of the sides and divide by four
