Answer:

<em>18x² - 84x + 96</em>

Step-by-step explanation:

(5 × 2 - 6x + 2) × (4 × 2 - 3x)

5 × 2 (4 × 2 - 3x) - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 6x(4 × 2 - 3x) + 2(4 × 2 - 3x)

80 - 30x - 48x + 18x² - 6x

96 - 84x + 18x²

18x² - 84x + 96

Hope this helps! :)

GIVING BRAINLIEST 9 POINTS AND FIVE STARS IF CORRECT!
Tema [17]

Answer:

Step-by-step explanation:

The colony of Pennsylvania was established by William Penn as a 'Holy Experiment'. It was given to him by the king in 1681, in payment of a debt he had to Penn's father. Amongst the other English colonies, Penn was the first leader of his colony that established peace with the natives. Then Penn made a peace treaty with the Leni lenape indians, and bought land from them. He hadn't needed to, but did anyways, and it was this act, as well as other kind acts towards the natives that formed peace between them. This also ensured a prosperous beginning for the new settlers of Pennsylvania, as the natives helped them with their crops, learning the way of the land and many such other useful things. Neither did they have wars that hurt the population. This is one of the reasons I'd want to live there, it is always good to have good relations, know what I mean? Philadelphia also means "Brotherly Love", I mean, who doesn't want to live in a place with such a groovy name?

The government was unlike that in most of the colonies in The New World. It allowed freedom of religion, even though Penn was a Quaker, and they tolerated everyones' individual beliefs. This also influenced the US's acceptance of every race and nationality. Legislative power in Pennsylvania was given to those elected by the colony. It gave people the freedom of choice, under the Concession. Thus the people were allowed a format of political freedom. The Frame of Government also proclaimed that capital punishment was to be given to those who had committed murder and crimes within that scope. Then in 1775 Pennsylvania was governed as a Proprietary Colony.Though this political view did not last forever, the time of prosperity under these laws was great. The United States Constitution is the supreme law of the United States of America. The Constitution, originally comprising seven articles, delineates the national frame of government, and it is mainly influenced by Philadelphia's form of government.

I hope that is what you're looking for, and it was enough info! :D

Please help me out with this geometry
Natalka [10]

Answer:

(x-[-7])^{2} +(y-[9])=[25]

Step-by-step explanation:

Center (h,k) = (-7, 9)

Radius, r = 5

<u>Equation</u>: (x-h)^{2} +(y-k)^{2} =r^{2}

(x-(-7))^{2} +(y-9)^{2} =(5)^{2}

5^{2} =25

So, (x-(-7))^{2} +(y-9)=25

. Write the equation for a circle with center (0, −4) and radius 8.
balu736 [363]
<h2>Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0</h2>

Step-by-step explanation:

Equation of circle with (h,k) as center and radius r is given by,

          (x-h)²+(y-k)² = r²

Here we need to find equation for a circle with center (0, −4) and radius 8.

Center = (h,k) = (0, −4)

Radius = r = 8

Substituting in equation

              (x-h)²+(y-k)² = r²

               (x-0)²+(y-(-4))² = 8²

               x²+(y+4)² = 64

                x²+y²+8y+16 = 64

                x²+y²+8y-48 = 0

Equation for a circle with center (0, −4) and radius 8 is x²+y²+8y-48 = 0
