Simplify the expression (5+3i)(4-4i) need help ASAP! Please

Can someone help me & explain, please?

Put the numbers in the data set in order from smallest to largest:

44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56

The smallest number is 44, the largest is 56, so the outside lines need to be above those numbers.

Both A and B have that.

Now find the median ( the average of the middle two numbers)

The middle two numbers from the list are 50 and 50 so the median would be (50 +50) /2 = 100/2 = 50

The middle line inside the rectangle needs to be above 50.

This makes the answer A.

Simply the monomials below (-8x⁴ y³)•(2x⁵ y²)+7x⁹ y⁵

vlada-n [284]

Answer:

-9x^9y^5

Step-by-step explanation:

Do the multiply first:

-16x^9y^5+7x^9y^5

=x^9y^5(-16+7)

=-9x^9y^5

Which sequence of transformations will map figure K onto figure K′? Two congruent kites, figure K and figure K prime, are drawn

elixir [45]

Answer:

The sequence of transformations will map figure K onto figure K′

is the first sequence option (1)

======================================================

Step-by-step explanation:

See the attached figure

as shown in the figure the K' is the image of K by reflection over x-axis

But  We need to know which sequence of transformations will give the same result.

So, we will test the options by any point from K and its image from K'

i.e: we will test the options using the points (6,5) , (6,-5)

(6,5) ⇒ (6,-5)

option (1):

Reflection across x = 4, 180° rotation about the origin, and a translation of (x + 8, y)

(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (6,-5)

option (2):

Reflection across x = 4, 180° rotation about the origin, and a translation of (x − 8, y)

(6,5) ⇒ (2,5) ⇒(-2,-5) ⇒ (-10,-5)

option (3):

Reflection across y = 4, 180° rotation about the origin, and a translation of (x + 8, y)

(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (2,-3)

option (4):

Reflection across y = 4, 180° rotation about the origin, and a translation of (x − 8, y)

(6,5) ⇒ (6,3) ⇒ (-6,-3) ⇒ (-14,-3)

As shown: The sequence of transformations will map figure K onto figure K′

is the first sequence option (1)
