Evelyn’s photo will not retain the same proportions.

<h3>What is the Scale of enlargement?</h3>

When we talk of scale of enlargement, we are simply referring to a transformation where we dilate the object by a scale factor. What this means is that all dimensions of the new object must have the same scale with corresponding dimensions of initial object.

Now, when we enlarge a 5” x 7” photograph to fit into a frame of 16” x 20”, then both corresponding sides must have same ratio or scale of enlargement.

Let us check the scales of enlargement;

16"/5" = 3.2 as scale factor

20/7 = 2.857 as scale factor

Thus, we can conclude that Evelyn’s photo will not retain the same proportions.

What is the difference of the polynomials? (â€""2x3y2 4x2y3 â€"" 3xy4) â€"" (6x4y â€"" 5x2y3 â€"" y5) â€""6x4y
zlopas [31]

Polynomial-An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable. The difference between the given polynomials is

=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

Given-

We have given two function of variable <em>x </em>and <em>y</em>

(-2x^3y^2 + 4x^2y^3-3xy^4)

(6x^4y-5x^2y^3-y^5)

<h3>Polynomial</h3>

An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.

Now we have to subtract the two equations to find the difference,

(-2x^3y^2 + 4x^2y^3-3xy^4)-(6x^4y-5x^2y^3-y^5)

Multiply the sign into the bracket to open the bracket and further solution,

=-2x^3y^2 + 4x^2y^3-3xy^4-6x^4y+5x^2y^3+y^5

Arrange the similar terms in the same groups,

=-2x^3y^2 + (4x^2y^3+5x^2y)-3xy^4-6x^4y+y^5=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

Hence, the difference between the given polynomials is=-2x^3y^2 + 9x^2y^3-3xy^4-6x^4y+y^5

Use elimination to solve!!!!!!
REY [17]
For easier notation lets use: Nn=x and Nd=y

x+y=22
5x+10y=135

Multiply the first equation by 5 to get
5x+5y=110

Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17

Michelle is performing the following construction. Based on the markings that are present, what construction is she performing?
IrinaVladis [17]
<h2>Answer:</h2>

B. Bisecting a line segment

<h2>Step-by-step explanation:</h2>

You forgot to include the construction, so I'll explain how to bisect a line. There are several steps you must follow in order to get this problem solved. First, suppose we have a line segment \overline{AB} as shown in the Figure below. If Michelle want to bisect this line segment, she would need to follow these steps:

1. She should choose one end of line segment and place on it.

2. She has to adjust the a bit longer than half the line segment length

4. Next, she must draw two arcs, one of them above and the other below the line.

5. She need to draw arcs from other end of line, but keeping the same compass width.

6. She should draw a line using a ruler where the arcs cross.
