Answer:

<h2>2. Combining old and new observations.</h2>

Step-by-step explanation:

Through the passage, Nicholas Copernicus is introducing to the reader a new worlds, based on observations from the pass, and recent observations made by scientists. Basically, he's talking about a work where the reader is going to able to learn and be aware about the stars and planets movements in a way that no one could imagine before.

Copernicus specifically states that those observations are based on ancient and new data.

Therefore, the right answer is 2, because it's a combination of old and new observations.

Use cross products to demonstrate whether the two ratios are equivalent in this problem: 4 over 6 times 14 over 21

ExtremeBDS [4]

4/6 = 14/21 When using cross product always multiply the left fractions numerator times the right side fractions denominator and the left side fractions denominator times the right side fractions numerator 4×21 = 6×14 84=84 They are equivalent because they both equal 84

Write and simplify an algebraic expression to represent the area of the shaded region. The image is below.

Lena [83]

$(x+2)^2 - 1\cdot(x-5) = x^2 + 2\cdot2x + 2^2 - (x - 5) = x^2 + 4x + 4 - x + 5 = x^2 + 3x + 9$

EGF and GFH are a linear pair, m EFG = 4n + 15, and m GFH = 5n + 39. what are m EFG and m GFH?

Tasya [4]

The angles of ∠EFG and ∠GFH are 71° and 109°

<h3>What are linear pair angles?</h3>

Linear pair of angles are formed when two lines intersect each other at a single point.

In other words, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other.

Linear pair angles are supplementary. This means the sum of a linear pair angles is 180 degrees.

Therefore,

∠EFG + ∠GFH = 180

Therefore,

∠EFG = 4n + 15

∠GFH = 5n + 39

hence,

4n + 15 + 5n + 39 = 180

9n + 54 = 180

9n = 180 - 54

9n = 126

n = 126 / 9

n = 14

Hence,

∠EFG = 4n + 15 = 4(14) + 15 = 71°

∠GFH = 5n + 39 = 5(14) + 39 = 109°
