how do u solve problems like this ?

Answers

Step by step explanatio:

The first and second polygons are exactly the same, the only difference is that the second is bigger! If we look right the first polygon is 4 cm and the second is triple which means that we will have to triple the area of ​​the First polygon to discover the area of ​​the second polygon!

Resposta:

if the first polygon is 4 cm long and the second 12 cm means that the second polygon has three times the area of ​​the first polygon!

[tex](4 cm.3=12 cm)\\A-10 cm^{2}.3=30 cm^{2}[/tex]

the second polygon has [tex]30 cm^{2}[/tex]  of area

[tex]A=30 cm^{2}[/tex]

how did the declaration of independence lead to the organ of what is now the US government?

3-5 sentences please:)

(put in wrong subject because i need this answer asap so sorry if anyone gets mad over this)

Answers

The Declaration of Independence gave birth to what is known today as the United States of America. The declaration helps the leaders and/or government lead our country. If we didn’t have it we wouldn’t have the laws we have today, we wouldn’t be able to have fire arms, women wouldn’t be able to vote, and so many other things. The document is symbolic of American democracy and one of the free charters of freedom. The words stated in the Declaration rallied support from colonists at home, and colonists living abroad.

Find the missing angle or find X?

Answers

Answer:

x = 45

Step-by-step explanation:

Interior angles of a triangle sum up to 180

180 - 90 = 90

90 / 2 = 45

Answer:

X = 45

Step-by-step explanation:

Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,

90+45+45=180

4) solve for n, show all work

—6 ( — 2 n + 4 ) = 24

Answers

Answer: n = 4

Step-by-step explanation:

-6(-2n + 4) = 24 (divide both sides by -6)

-2n + 4 = -4 (subtract 4 from both sides)

-2n = -8 (divide by -2 on both sides)

n = 4

Answer:

12n - 24 = 24

add 24 to both sides

12n = 48

divide 12 from both sides

n = 4
