Answer:

30cm

Step-by-step explanation:

Because of the polygon similarity postulate (PSP) 8/12=20/x

8/12=20/x

20/(8/12)=x

20*12/8=x

x=30 cm

The length of side x is 30 cm when the shapes below are mathematically similar.

To calculate the length of side x, we can use the concept of similarity between the shapes. When two shapes are mathematically similar, their corresponding sides are proportional.

8 cm corresponds to 20 cm

12 cm corresponds to x (unknown)

Using the concept of proportionality, we can set up the following equation:

(8 cm) / (20 cm) = (12 cm) / (x)

To find x, we can solve this equation:

Cross-multiplying:

8 cm * x = 20 cm * 12 cm

Simplifying:

8x = 240 cm²

Dividing both sides by 8 to isolate x:

x = 240 cm²/ 8

x = 30 cm

Therefore, the length of side x is 30 cm.

12 am is right above 9 pm but it occurs before 9pm.

Using the density concept, it is found that the mass would stay the same, and the correct option is given by B.

Step-by-step explanation:

The quadratic function [tex]f(x)[/tex] has one zero at [tex]x=-5[/tex] and a turning point at [tex](3,10)[/tex]. The value of other zero is [tex]11[/tex].

The Quadratic function [tex]f(x)[/tex] is a polynomial function with one or more variables in which the highest power of the variable is two. i.e.  [tex]f(x) = ax^{2} + bx + c[/tex]

The zeros of a polynomial [tex]f(x)[/tex] are all the [tex]x[/tex]-values that make the polynomial equals to zero. i.e. [tex]f(x)=0[/tex]

A turning point is a point at which the derivative changes sign.

We have,

One zero is  [tex](-5)[/tex],

Let other Zero be [tex]"a"[/tex],

Turning point at [tex](3,10)[/tex].

i.e. [tex]x=3[/tex] and [tex]y=10[/tex]

Since the difference between [tex]3[/tex] and [tex](-5)[/tex] is [tex]8[/tex].

So,

The difference between the other zero from [tex]3[/tex] should be the same as the difference between [tex]3[/tex] and [tex](-5)[/tex].

i.e.

[tex]a-3=8[/tex]

[tex]a=11[/tex]

Hence the value of its other zero is [tex]11.[/tex]

Answer:

I. Length, L = 11 cm

II. Width, W = 6 cm

Step-by-step explanation:

Let the length of the rectangle be L.

Let the width of the rectangle be W.

Given the following data;

Area of rectangle = 66 cm²

Translating the word problem into an algebraic expression, we have;

L = 2W - 1 .....equation 1

We know that the area of a rectangle is given by the formula;

A = L * W

Substituting

66 = L * W ....equation 2

Substituting eqn 1 into eqn 2, we have;

66 = (2W - 1) * W

66 = 2W² - W

2W² - W - 66 = 0

Note: the standard form of a quadratic equation is ax² + bx + c = 0

a = 2, b = -1 and c = -66

Solving the quadratic equation using the quadratic formula;

The quadratic equation formula is;

[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]

Substituting into the equation, we have;

[tex] x = \frac {-(-1) \; \pm \sqrt {1^{2} - 4*2*(-66)}}{2*2} [/tex]

[tex] x = \frac {1 \pm \sqrt {1 - (-528)}}{4} [/tex]

[tex] x = \frac {1 \pm \sqrt {1 + 528}}{4} [/tex]

[tex] x = \frac {1 \pm \sqrt {529}}{4} [/tex]

[tex] x = \frac {1 \pm 23}{4} [/tex]

[tex] x_{1} = \frac {1 + 23}{4} [/tex]

[tex] x_{1} = \frac {24}{4} [/tex]

x1 = 6

We do not need the negative value of x, so we proceed.

Therefore, Width, W = x1 = 6 cm

Next, we find the length L;

From eqn 1;

L = 2W - 1

L = 2(6) - 1

L = 12 - 1

L = 11 cm

Answer and Step-by-step explanation:

The actual answer is 348.

I disagree with this quote. I think this quote means that good men should relax and make the others do the work.  I think it could be hard at times for good men should to speak up for a couple of reasons. I think it could be hard for men to speak up because they could be embarrassed or at certain times they wouldn't know what to do so they would freak out. Just because it may be hard to speak up doesn't mean they should be lazy and relax, they should still help in my opinion.

Answer:

90 [tex]cm^{2}[/tex] of blue paint

Step-by-step explanation:

From the given diagram, the sides have the same dimensions and the shape of a triangle.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

Given that, the base of each side = 6 cm, and the height = 10 cm.

Then,

Area of each side of the shape = [tex]\frac{1}{2}[/tex] x 6 x 10

                                              = 30 [tex]cm^{2}[/tex]

Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;

3 x area of each side = 3 x 30

                                   = 90 [tex]cm^{2}[/tex]

Leonard would need 90 [tex]cm^{2}[/tex] of paint to paint the sides of the shape.
