give a numerical example that shows these are not the same expressions. 2(n+5) and 2n+5

Answers

Answer:

The two are different expressions because when you distibute, you multiply all terms inside the parenthesis with the 2 in the first one: 2(n+5) = 2n + 10.

2n + 10 ≠ 2n + 5.

Step-by-step explanation:

Answer: Any number that isn’t 1, 2, -1, or -2 I believe.

Step-by-step explanation: In the first expression, you have to distribute the 2, making it equal to 2n + 10, whereas the first is just 2n + 5.

For example if you were to plug the number 3 into this, you would have 2(3+5), which is 2(8) = 16. Versus the other side, 2(3)+5 = 11

Step-by-step explanation:

The vertices of image A'B'C' after dilation with a scale factor of 2 about the origin are , A' (6, -2), B' (4,2), and C' (10, 6).

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

ABC has vertices A (3, -1), B (2, 1), and C(5, 3).

Now, After dilation with a scale factor of 2 about the origin the vertices of A', B' and C' are,

A' = 2 × (3, - 1)

   = (6, - 2)

B' = 2 × (2, 1)

   = (4, 2)

C' = 2 × (5, 3)

    = (10, 6)

82.40 - 24.72 = 57.68

The dimensions of a rectangular monitor screen are such that it's length is 5 in. More than it's width. If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in^2. What are the length and width of the screen?

Answers

Given:

Length of a rectangular monitor screen is 5 in more than it's width.

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

To find:

The length and width of the screen.

Solution:

Let width of the screen be x inches.

Length of a rectangular monitor screen is 5 in more than it's width. So,

Length of screen = (x+5) inches

Area of screen is

[tex]Area=length\times width[/tex]

[tex]A_1=(x+5)\times x[/tex]

[tex]A_1=x^2+5x\text{ in}^2[/tex]

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

New length = 2(x+5) inches

New width = (x-1) inches

So, new area is

[tex]A_2=2(x+5)(x-1)[/tex]

[tex]A_2=(2x+10)(x-1)[/tex]

[tex]A_2=2x^2+10x-2x-10[/tex]

[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]

Area increased by  170 in².

[tex]A_2-A_1=170[/tex]

[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]

[tex]2x^2+8x-10-x^2-5x=170[/tex]

[tex]x^2+3x-10=170[/tex]

Subtract 170 from both sides.

[tex]x^2+3x-10-170=0[/tex]

[tex]x^2+3x-180=0[/tex]

Splitting the middle term, we get

[tex]x^2+15x-12x-180=0[/tex]

[tex]x(x+15)-12(x+15)=0[/tex]

[tex](x+15)(x-12)=0[/tex]

[tex]x=-15,12[/tex]

Width cannot be negative. So, x=12.

Width = 12 inches

Length = 12+5 = 17 inches

Therefore, the length of screen is 17 inches and width is 12 inches.
