Answer:

9c^2 - 30cd + 25d^2

Step-by-step explanation:

(3c - 5d)^2

= (3c - 5d) (3c - 5d)

= [3c * 3c] + [3c * -5d] + [-5d * 3c] + [-5d * -5d]

= 9c^2 - 30cd + 25d^2

The value of x that will make the considered parallelogram ABCD a rhombus is 4 units.

Rhombus is a parallelogram whose all sides are of equal lengths.

For this problem, the missing figure is attached below.

We see that the angle between the diagonals is [tex](3x- 12)^\circ[/tex]

It is given that ABCD is a parallelogram.

For ABCD parallelogram to be a rhombus, its diagonals need to be perpendicular to each other.

Perpendicular lines have 90° angle between them.

Thus, we need:

[tex](3x- 12)^\circ = 90^\circ[/tex]

Evaluating value of x:

[tex](3x- 12)^\circ = 90^\circ\\3x - 12 = 90\\\text{Adding 12 on both the sides}\\3x = 102\\\text{Dividing both the sides by 3}\\\\x = 12/3 = 4[/tex]

Thus, the value of x is 4

The total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.  

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Let x be the total number of toy cars in Enola's collection:

69% of x = x - 155

0.69x = x - 155

0.31x = 155

x = 500

Thus, the total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Step-by-step explanation:

to find the answer you can first add all the books together

this can be represented by

3 + 2 + 2.5 + 1.5

this answer is 9

then multiply it by 6

9 * 6 = 54

is is c

Step-by-step explanation:

All we have to do is apply the Pythagorean theorem which states that a²+b²=c²

where c is the hypotenuse of the triangle or the side facing the 90° angle.

Moreover a & b are the other two sides of the triangle.

[tex]11 {}^{2} = {9}^{2} + h {}^{2} [/tex]

where h is the height from the ground

[tex]121 = 81 + {h}^{2} [/tex]

[tex]h {}^{2} = 121 - 81[/tex]

[tex]h {}^{2} = 40[/tex]

[tex]h = \sqrt{40} = 6.324[/tex]

Rounding to the nearest tenth,

[tex]y=\dfrac{2xz}{(z-x)}[/tex]

Step-by-step explanation:

Given:

[tex]\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{1}{x}-\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{z-x}{xz}[/tex]

[tex]\implies 2xz=y(z-x)[/tex]

[tex]\implies y=\dfrac{2xz}{(z-x)}[/tex]

When x = 5 and z = 10:

[tex]\implies y=\dfrac{2(5)(10)}{(10-5)}[/tex]

[tex]\implies y=\dfrac{100}{5}[/tex]

p = 23

q = 18

Step-by-step explanation:

The four interior angles of a square are all 90° each

 4p - 2 = 90

⇒ 4p = 92

⇒ p = 92 ÷ 4

⇒ p = 23

 5q = 90

⇒ q = 90 ÷ 5

⇒ q = 18

Answer:

p=23; q=18.

Answer:

(√3 - x)(√3 + x)

Step-by-step explanation:

Use difference of two square formula:

a² - b² = (a - b)(a + b)

and  b² = x²  ⇒  b = x

Therefore, 3 - x² = (√3 - x)(√3 + x)
