Select the correct answer. Simplify the following expression. 3x(4x − 3) please help meh

Answer:

x=4

Step-by-step explanation:

The left and right sides are equal so:

5x-2 + 4x = 7x-4 + x+6

Collect the like terms and calculate the sum :

9x-2 = 8x+2

Move terms and change it's sign:

9x-8x = 2+2

And finally:

x=4

Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4

which the intersection with the previous answer will be x=4

Surface area of the prism given is 46 inches².

The area of a three dimensional object on it's outer surface is called the surface area of the object

Given net of a prism.

The given net consists of three rectangles and two triangles.

Find the area of each of the two dimensional figures.

Given, the bases are isosceles triangles.

So the two rectangles are of dimensions 5 inch × 2.5 inch and third rectangle is of the dimensions 5 inch × 3 inch.

Total area of the rectangles = (5 × 2.5) + (5 × 2.5) + (5 × 3)

                                              = 40 inches²

Area of two triangles = 2 × [tex]\frac{1}{2 }[/tex] × 3 × 2

                                   = 6 inches²

Surface area of the prism = 40 inches² + 6 inches² = 46 inches²

Hence the required area is 46 inches².

The equation is "[tex]y=6 \ Cos(\frac{12}{5}x)-5[/tex]". A further explanation is described below.

Step-by-step explanation:

The given values are:

Period,

B = [tex]\frac{5 \pi}{6}[/tex]

  = [tex]\frac{12}{5}[/tex]

Amplitude,

A = 6

Vertical translation down,

D = -5

As we know,

The equation of cosine function will be:

⇒  [tex]y=A \ Cos(Bx)+D[/tex]

On substituting the values in the above equation, we get

⇒  [tex]y=6 \ Cos(\frac{12}{5}x)+(-5)[/tex]

⇒  [tex]y=6 \ Cos(\frac{12}{5}x )-5[/tex]

[tex]3(10a + 13b)[/tex]

Step-by-step explanation:

1) Find the Greatest Common Factor (GCF).

GCF = 3

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

[tex]3( \frac{30a}{3} + \frac{39b}{3} )[/tex]

3) Simplify.

[tex]3(10a + 13b)[/tex]

Therefor, the answer is 3 ( 10a + 13b)

Given:

[tex]\cot \theta = -2[/tex]

To find:

The value of [tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex].

Solution:

We know that,

[tex]\cot (\theta -n\pi)=\cot \theta[/tex]         ...(i)

Where n is an integer.

We have,

[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex]

Using (i), it can be written as

[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=\cot \theta +\cot \theta +\cot \theta [/tex]

[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3\cot \theta[/tex]

It is given that [tex]\cot \theta = -2[/tex].

[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3(-2)[/tex]

[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=-6[/tex]

Therefore, the value of the given function expression is [tex]-6[/tex].

Answer:

0.079

Step-by-step explanation:

Number of suit of hearts = 13

Total number of cards in deck = 52

P(drawing a suit of heart) = number of suit of heart / total number of cards in deck

P(drawing a suit of heart) = 13 /52 = 1 /4

Hence, Probability of success, p = 1/4

P(not drawing a suit of heart) = 1 - 1/4 = 3/4

Hence, Probability of performing exactly 5 draws :

To perform exactly 5 draws :

1st draw = not a heart suit

2nd draw = not a heart suit

3rd draw = not a heart suit

4th draw = not a heart suit

5 draw = a heart suit

P(performing exactly 5 draws) =

(3/4 * 3/4 * 3/4 * 3/4 * 1/4)

= 0.0791015625

= 0.079

Step-by-step explanation:

V=hb/3, where b=area of base

b=3V/h, since V=30mm^3 and h=5mm then

b=3(30)/5

b=18 mm^2

So the area of the base is 18 square millimeters.
