Answer:

The quadrilateral ABCD is a square.

Step-by-step explanation:

According to the statement, AB, BC, CD and DA are the sides of the quadrilateral, whereas DB and AC are its diagonals. If we know that x = 7, AB = 4\cdot x - 2, BC = 2\cdot x + 12, DC = 3\cdot x +5, AD = 6\cdot x -16, AC = 4\cdot x + 12 and DB = 8\cdot x -10, the lengths of each line segment are respectively:

Sides

AB = 4\cdot (7) -2

AB = 26

BC = 2\cdot (7) +12

BC = 26

DC = 3\cdot (7) +5

DC = 26

AD = 6\cdot (7) -16

AD = 26

Diagonals

AC = 4\cdot (7) +12

AC = 40

DB = 8\cdot (7) - 10

DB = 40

This information indicates that this quadrilateral is a square because of these characteristics:

1) All sides have the same length.

2) The ratio of any diagonal to any side is \sqrt{2}.

Multiply (6 − 7i)(3 − 6i).
Leviafan [203]

Answer:

-24 - 57i

Step-by-step explanation:

i'm assuming that this is a question about imaginary numbers and that i²= -1

we can expand the binomial by using the FOIL method (see attached)

(6 − 7i)(3 − 6i)

= (6)(3) + (6)(-6i) + (-7i)(3) + (-7i)(-6i)

=18 - 36i - 21i + 42i²   (recall that i²= -1)

= 18 - 57i + 42(-1)

= 18 - 57i - 42

= -24 - 57i
