The value of x is 108.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the HCF of 90 and x is 18.

And the LCM of 90 and x is 540.

We have to determine the value of x.​

Since the product of two numbers equals the product of their HCF and LCM.

So 90 × x= HCF × LCM

Substitute the values of given data,

⇒ 90×x = 18×540

⇒ 90×x = 9720

⇒ x = 9720/90

⇒ x = 108

Hence, the value of x is 108.

[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]

Answer:

A

Step-by-step explanation:

We want to simplify the expression:

[tex](4 + 2i)(4- 2i)[/tex]

Notice that this is the difference of two squares. That is:

[tex](a +b)(a-b) = a^2 - b^2[/tex]

We can let a = 4 and b = 2i. Hence:

[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]

Simplify:

[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]

(Note that i² = -1.)

In conclusion, our answer is A.

The required algebraic expression is c+4

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given that a statement 4 plus c as an algebraic expression

We need to convert it into an expression,

4 = 4

plus = +

c = c

Therefore, arranging it = c+4

Hence, the required algebraic expression is c+4

A point of intersection of two or more planes is the point where the plane meet. The answers to the questions are:

17) Point S

18) Point V

19) Point V

20) Point T

A plane is a flat surface which lies or can either be considered with respect to the x- axis, y- axis or z- axis. An intersection of two planes implies the point where the two planes meet.

From the given figure, the given planes has their points of intersections. Thus, the intersection of the planes given in the question are as follows:

17) planes QRS and RSW - The point of intersection of these two planes is point S.

18) planes UXV and WVS - The two planes has the point of their intersection as V.

19) planes XWV and UVR - The point of intersection of the planes is V.

20) planes TXW and TQU - The two planes intersect at point T.

Each of these planes has to be considered separately before relating it to another plane.

Answer:

[tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

By subtracting x³ - 3x² + x - 1 , that is

[tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - (x³ - 3x² + x - 1) ← distribute by - 1

= [tex]x^{4}[/tex] + 5x³ - 6x² - 5x - 2 - x³ + 3x² - x + 1 ← collect like terms

= [tex]x^{4}[/tex] + 4x³ - 3x² - 6x - 1

Step-by-step explanation:

x⁴ + 5x³ - 6x² - 5x - 2

should become

x³ - 3x² + x -1

so, what do I need to subtract from the top terms to get the bottom terms ?

because we can only look from one x- term to the next. we can only combine them, when they have the same x exponent.

so, we see there is no x⁴ in the desired result.

therefore, we know as a first item that x⁴ had to be subtracted.

the next x exponent is 3.

we have 5x³ on the top, and x³ on the bottom.

so, clearly, we need to subtract 4x³ as second term.

the next x exponent is 2.

we have -6x² on the top, and -3x² on the bottom.

so, we should actually add 3x². and how do we do this in a subtraction ? by subtracting a negative value, which actual adds it.

so, we need to subtract -3x² as third term.

the next x exponent is 1 (just x).

we have -5x on the top and x on the bottom.

so, the same trick as before, as we need to add something.

so, we need to subtract -6x as fourth term.

and finally, the x exponent 0, which just shows the constant numbers.

we have -2 on the top and -1 on the bottom.

again the same trick to actually add 1.

we need to subtract -1 as fifth term.

so, in total, this is what we need to subtract from the top line to get the bottom line :

x⁴ + 4x³ - 3x² - 6x - 1
