A:

16a^2-24a+9

16a^2-12a-12a+9

4a(4a-3)-3(4a-3)

(4a-3)(4a-3)

(4a-3)^2

(4a-3)^2

B: Use difference of squares method

(3a+5b)(3a−5b)

Part A: The length of each side of the square is (4a - 3) units.

Part B: The dimensions of the rectangle are (3a + 5b) units (length) and (3a - 5b) units (width).

Part A:

The area of a square is given by the formula A = s^2, where "s" is the length of each side of the square. In this case, the area is (16a² - 24a + 9) square units.

To determine the length of each side of the square, we need to factor the area expression completely and set it equal to (s^2).

The area expression is a quadratic trinomial: 16a² - 24a + 9.

To factor the trinomial, we look for two binomials that, when multiplied together, give us the original trinomial. The binomials will have the form: (ma ± b)(na ± c).

To factor 16a² - 24a + 9, we look for two numbers whose product is 16 * 9 = 144, and whose sum is -24 (the middle coefficient).

The two numbers are -12 and -12 because (-12) * (-12) = 144 and (-12) + (-12) = -24.

Now, rewrite the middle term (-24a) using -12a - 12a:

16a² - 12a - 12a + 9

Group the terms and factor by grouping:

(16a² - 12a) - (12a - 9)

Now, factor out the greatest common factor (GCF) from each group:

4a(4a - 3) - 3(4a - 3)

Now, notice that we have a common binomial factor of (4a - 3):

(4a - 3)(4a - 3)

Since both binomials are the same, we can rewrite it as (4a - 3)^2.

Now, set (4a - 3)^2 equal to (s^2):

(4a - 3)^2 = s^2

To find the length of each side (s), take the square root of both sides:

√((4a - 3)^2) = √(s^2)

4a - 3 = s

Therefore, the length of each side of the square is (4a - 3) units.

Part B:

The area of a rectangle is given by the formula A = length * width. In this case, the area is (9a² - 25b²) square units.

To determine the dimensions of the rectangle, we need to factor the area expression completely and identify the length and width.

The area expression is a difference of squares: 9a² - 25b².

To factor a difference of squares, we use the formula: a² - b² = (a + b)(a - b).

In this case, a = 3a and b = 5b:

9a² - 25b² = (3a + 5b)(3a - 5b)

Therefore, the dimensions of the rectangle are (3a + 5b) units (length) and (3a - 5b) units (width).

Answer:

The sandbox is most likely in the shape of a kite. As it has only two right angles, it cannot be a square or other form of rectangle. It also cannot be a parallelogram, which has no right angles, nor is it a rhombus- all four sides are not of the same length.

A kite, however, has two pairs of equal-length sides that are adjacent to each other. It also has two sets of equal-measure angles, one of which can be 90° if it is a cyclic kite.

====================================================

Reason:

[tex]2^6[/tex] means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say

[tex]2^6 = (2*2*2)*(2*2*2)[/tex]

The parenthesis are optional, but I find they're handy to count the '2's easier.

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

Now notice that

[tex]2^3 = 2*2*2[/tex]

So,

[tex]2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2^3)*(2^3)\\\\2^6 = (2^3)^2\\\\[/tex]

The last step is possible because we have two copies of [tex]2^3[/tex] multiplied together.

This shows that choice C is equivalent to A and B.

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

Lastly,

[tex]2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2*2)*(2*2)*(2*2)\\\\2^6 = (2^2)*(2^2)*(2^2)\\\\2^6 = (2^2)^3\\\\[/tex]

The jump to the last step is possible because we have three copies of [tex]2^2[/tex] multiplied together.

This shows choice D is equivalent to the others.

All four expressions are the same.

They represent different ways to say the same number. That number being 64.

S₄₀ = 2780

Step-by-step explanation:

there is a common difference between consecutive terms in the sequence, that is

14 - 11 = 17 - 14 = 3

this indicates the sequence is arithmetic with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 11 and d = 3 , then

S₄₀ = [tex]\frac{40}{2}[/tex] [ (2 × 11) + (39 × 3) ]

      = 20( 22 + 117)

Putting the considered items in order from most expensive to least expensive item gives the order as shown by: Option b. Blender, ink, hat, heater

Markup is the amount that will be increased in the original price of the considered thing.

Markdown is the amount that will be decreased from the original price of the considered thing.

Think of "up" and "down" as increasing and decreasing prices respectively.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, the base prices and the chage in price is given as:

Item                Base Price                    Change Direction

Heater             $28.46                           22% Markdown

Calculating the resultant price:

Resultant price = 29.73 - 9% of 29.73

[tex]P= 29.73 - \dfrac{29.73}{100}\times 9\\\\P = 27.0543 \: \: \text{dollars}[/tex]

Resultant price = 20.17 + 27% of 20.17

[tex]P= 20.17+\dfrac{20.17}{100}\times 27\\\\P = 25.6159\: \: \text{dollars}[/tex]

Resultant price = 28.46 - 22% of 28.46

Answer:

B)  width = 4 ft

    length = 9 ft

Step-by-step explanation:

Area = 36 ft²

Let width = x

⇒ length = x + 5

Area of a rectangle = width × length

⇒ 36 = x(x + 5)

⇒ x² + 5x - 36 = 0

⇒ x² + 9x - 4x - 36 = 0

⇒ (x² + 9x) + (-4x - 36) = 0

⇒ x(x + 9) - 4(x + 9) = 0

⇒ (x + 9)(x - 4) = 0

⇒ x = -9, x = 4

As distance is positive, x = 4 only

Therefore,

width = x = 4 ft

length = x + 5 = 4 + 5 = 9 ft
