Answer:

the answer is 100% 3

Step-by-step explanation:

Answer:

a) The polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.

b) The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].

Step-by-step explanation:

a) By Geometry, we know that area of the square is equal to the square of the side length. If [tex]A = x^{2}-30\cdot x +225[/tex] is the area of the square, then must be a perfect square trinomial, that is:

[tex](x-a)^{2} = x^{2}-2\cdot a\cdot x + a^{2}[/tex] (1)

Then, we must observe the following properties:

[tex]-2\cdot a = -30[/tex] (2)

[tex]a = 15[/tex]

[tex]a^{2} = 225[/tex] (3)

[tex]a = 15[/tex]

Therefore, the polynomial is equivalent to [tex]A = (x-15)^{2}[/tex], and the side length of the playground is [tex]x -15[/tex] feet.

b) The perimeter of a square equals four times the side length. That is:

[tex]p = 4\cdot (x-15)[/tex]

The perimeter of the playground, measured in feet, is [tex]p = 4\cdot (x-15)[/tex].

The polynomial that represents the side length is x - 15, and the perimeter of the playground is 4x - 60

The expression of the area is given as:

[tex]A = x^2 - 30x + 225[/tex]

Expand the expression

[tex]A = x^2 - 15x - 15x + 225\\[/tex]

Factorize

[tex]A= (x - 15)^2[/tex]

The area of a square is:

[tex]A = l^2[/tex]

Where l represents the side length.

So, we have:

[tex]l = x - 15[/tex]

The perimeter is then calculated as:

[tex]P = 4l = 4*( x - 15)[/tex]

[tex]P = 4x - 60[/tex]

Hence, the perimeter of the playground is 4x - 60

634.4   so the standard form is 600  + 30  + 4  + 0.4

Answer:

634.4 or 6.344*10^2

Step-by-step explanation:

When you're being asked to write an expression in standard form, the question probably wants you to simplify the expression or write it in scientific notation

Usually, in lower levels, you would simplify the expression, in which case you would multiply 6.1 by 104 using either a calculator (if you're allowed) or on paper to get 634.4

If you think your teacher wants you to use scientific notation, you would want to write your expression as a number under 10 multiplied by a power of 10. For example, if you were looking to write 6*8 in scientific notation/standard form, you would simplify for a product of 48, and turn that into 4.8*10. In your problem, you can multiply 6.1*104, and write your product of 634.4 as 6.344*10^2

Answer:

D.) The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.

Step-by-step explanation:

So the first thing we have to do is look at the information given, we know that the shape on the left is translated into the shape on the right. When a shape is "translated" it simply means that the shape doesn't change in size or rotation it only glides or moves. So the shape on the right is the former shape and the shape on the left is the pre-image.

Knowing that the left shape is the pre-image goes ahead and eliminates answer choices B & C as both answers mention that the right side is the image before the transformation which because of what was previously mentioned, is incorrect.

This leaves only answer choices A and D. Finally we can narrow down the final answer by knowing that the apostrophe " ' " or prime should be placed after each letter not just at the end of letters. For example A'B'C'D' not ABCD'. If we apply this rule to the last to answer choices we can see that D is the correct answer.

Answer:

$93.6

Step-by-step explanation:

The original price if this show is to be sold at $156

But the question tells us that everything is being sold with a 40% off.

So we should get 40% of 156

= 0.40 * 156

= $62.4

So this shoe would have it's new price to be $(156 - 62.4) = $93.6

So in conclusion given a 40 percent off, the sales price if the shoe would be $93.6

Answer: 8/14

Step-by-step explanation:

Given:

12% decrease followed by a 18% increase.

To find:

The single percentage change is equivalent to the given set of percentages.

Solution:

Let the initial value be 100.

After 12% decrease, the value is:

[tex]v_1=100-\dfrac{12}{100}\times 100[/tex]

[tex]v_1=100-12[/tex]

[tex]v_1=88[/tex]

After 18% increase, the value is:

[tex]v_2=88+\dfrac{18}{100}\times 88[/tex]

[tex]v_2=88+15.84[/tex]

[tex]v_2=103.84[/tex]

The initial value  is 100 and the new value in 103.84. So, it represents  increase in the value. So, increase percentage is

[tex]Increase\%=\dfrac{\text{New -Initial}}{\text{Initial}}\times 100[/tex]

[tex]Increase\%=\dfrac{103.84-100}{100}\times 100[/tex]

[tex]Increase\%=3.84[/tex]

Therefore, the value increased by 3.84%.

Answer:

wildflower: $8

daffodil: $14

Step-by-step explanation:

9w + 9d = 198

2w + 5d = 86

         -18w - 18d = -396

(+)       18w + 45d = 774

----------------------------------

                    27d = 378

d = 14

9w + 9(14) = 198

9w = 72

w = 8

Answer:

(-5, -1), does not belong to the relation y = -x + 4

Step-by-step explanation:

From the question, we have;

The given ordered pair having a relation = (-5, -1)

The given relation, y = -x + 4

From the given relation, we get;

When y = -1

-1 = -x + 4

∴ -x = -1 - 4 = -5

x = 5

Similarly, when x = -5, we get;

y = -x + 4 = -(-5) + 4 = 5 + 4 = 9

y = 9

Therefore, (-5, -1), does not belong to the relation y = -x + 4 but (-5, -1), belongs to the relation y = x + 4
