Can someone pls write just a few sentences about this I lol give brainliest and 20 points

Answer:

Step-by-step explanation:

x² - 6x - 27

x² - 9x + 3x - 27

x(x - 9) + 3(x - 9)

(x - 9) (x + 3) = 0

x = 9

x = -3

The dimensions are 9 and 3

Answer:

B. a square must have 4 right angles, but a rhombus may or not have 4 right angles.

Answer:

B

Step-by-step explanation:

The main difference between a square and a rhombus is a square must have 4 right angles, but a rhombus may or may not have 4 right angles. All the angles of a square have to be 90 degrees. All right angles are 90 degrees. All squares are rhombuses, but not all rhombuses are squares. There are occasions when a rhombus has 4 right angles.

How to add complex numbers?

A complex number is a kind of number which has two parts:

The real part consists of real numbers whereas the imaginary part consists of numbers like i (iota=√-1)and its multiples.

When we add complex numbers, we add the real part and the imaginary part separately.

In this question:

Therefore, we get a new complex number that is √3+2+i(√3-1).

Step-by-step explanation:

thats right

The solution is d₁ = 24

The product of the elements on the main diagonal of the matrix is 24

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

Let the matrix be represented as A

Now , the value of A is

[tex]A = \left[\begin{array}{ccc}3 &2 \\ 5 &8 \\\end{array}\right][/tex]

Now , on simplifying the matrix A

The main diagonal of the matrix is having the elements ( a₁₁ ) and ( a₂₂ )

So , the product of the elements in the main diagonal is

a₁₁ = 3

a₂₂ = 8

And , the equation will be

d₁ = ( a₁₁ ) x ( a₂₂ )

Substituting the values in the equation , we get

d₁ = 3 x 8

d₁ = 24

Therefore , the value of d₁ is 24

Hence , the product of the diagonal elements of matrix is 24

The required measures of the circle are:

mDF = 75, m∠FBE 105, mFC=60
m∠CBE = 45, mDAC = 225. m∠ABE=135

m∠ABF=120

A section of a circle is a region enclosed by a chord and an arc of the circle. It is also called a circular sector. A circular sector is defined by its central angle, which is the angle between the two radii that form the sector, and its radius, which is the distance from the center of the circle to the endpoints of the sector.

Here,
A circle is shown,

mDF = 75  [shown in the image]

m∠FBE = 60 + ∠CBE

m∠FBE = 60 + ∠ABD     [∠ABD=∠CBE]

m∠FBE = 60 + 45             [∠ABD = 180 - 75-60]

m∠FBE = 105,

Similarly,

mFC=60, m∠CBE = 45, mDAC = 225, m∠ABE=135, and m∠ABF=120

Answer:

m = 8

Step-by-step explanation:

[tex]\frac{m}{12}[/tex] = [tex]\frac{10}{5+10}[/tex]

15m = 120

m = 8

Use csc (90) = 10/m.

So, m = 10/csc(90).

m = 8.93997

Answer: m = 8

Answer:

202m

Step-by-step explanation:

Use pythagoream theorum to find the hypotenuse. So [tex]a^{2} +b^{2} =c^{2}[/tex], where the height (40m)=a and the anchor length (198m)=b. That leaves us with  [tex]40^{2} +198^{2} =c^{2}[/tex], doing the math out for that we get 40,804=[tex]c^{2}[/tex], taking the square root of 40,804 we get our answer of 202m

Answer:

Area=12/7square yard

Step-by-step explanation:

Area=base x height

Area=3x4/7=12/7 square yard

Answer:

Area = 136

Step-by-step explanation:

Rectangle on the bottom

Length = 16

Width = 7

Area = L * W

Area = 16 * 7

Area = 112

Triangle on Top

Height = 13 - 7 = 6

Length = 16 - 8 = 8

In a right triangle the area = the product of the 2 shortest sides divided by 2

Area = 1/2 * Length * Height

Area = 1/2 * 8 * 6

Area = 1/2 48

Area = 24

Total Area = 112 + 24 = 136

Answer:

Answer:

the amount financed is $16,000

Step-by-step explanation:

The computation of the amount financed is shown below:

As we know that

Amount financed = cash price - down payment

= $16,500 - $500

= $16,000

Hence, the amount financed is $16,000

If we deduct the down payment from the cash price so we can get the amount financed

Answer:

16units

Step-by-step explanation:

Given data

The expression for the volume of a cone is given as

v=1/3πr^2h

v= 3π

r= 12

h=???

Substitute

3π= 1/3*π*12^2*h

3= 1/3*144*h

3= 144h/3

cross multiply

3*3= 144h

9= 144h

h= 144/9

h=16 units

Hence the heeight is 16units

AS:

If these cubes are to to be placed so that their respective faces are parallel

or perpendicular, as the case may be, to the respective orientations of the

dimensions of the box, without tilting any cubes in any directions,

then choice B) can be justified. This leaves spaces (some volume) in the box

not filled by the cubes.

How many whole number of edges of the cubes fit into 4 cm?  

4 / 3 √ 2   must be rounded down to 3.

How many whole number of edges of the cubes fit into 8 cm?  

8 / 3 √ 2   must be rounded down to 6.

How many whole number of edges of the cubes fit into 10 cm?  

10 / 3 √ 2   must be rounded down to 7.

Then (3)(6)(7) = 126
