6. Solve for x in each of the following equations:
a. m(x + n) =n

c. mx = n(m + x)​

Answer:The answer would be $1080.

Answer:

Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity.

Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…

Integers include all whole numbers and their negative counterpart e.g. …-4, -3, -2, -1, 0,1, 2, 3, 4,…

All integers belong to the rational numbers. A rational number is a number

ab,b≠0

Where a and b are both integers.

Example

The number 4 is an integer as well as a rational number. As it can be written without a decimal component it belongs to the integers. It is a rational number because it can be written as:

41

or

82

or even

−8−2

Whereas

15=0.2

is a rational number but not an integer.

A rational number written in a decimal form can either be terminating as in:

15=0.2

Or repeating as in

56=0.83333...

All rational numbers belong to the real numbers.

If you look at a numeral line

picture05

You notice that all integers, as well as all rational numbers, are at a specific distance from 0. This distance between a number x and 0 is called a number's absolute value. It is shown with the symbol

|x|

If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites. Opposites have the same absolute value since they are both at the same distance from 0.

|10|=10=|−10|

Answer:

1 1/4 more hours

Step-by-step explanation:

To find this, we must subtract 2 1/2, the time it takes you to get home with bad weather by 1 1/4, the amount it usually takes you to get home. We can make 2 1/2 into 2 2/4, and now we can subtract and get 1 1/4.

Answer:

[tex]\boxed{\textsf{ The value of x is }\bf{ \dfrac{-5\pm\sqrt{21}}{2}}.}[/tex]

Step-by-step explanation:

A quadratic equation is given to us and we need to find the Solutions of the quadratic equation . So the given equⁿ is ,

[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0 [/tex]

Firstly let's simpify the quadratic equation and then use the quadratic formula also known as " Shreedhacharya's Formula" .

Taking the given equation :-

[tex]\sf\implies (x+4)^2 -3(x+4) -3 = 0\\\\\sf\implies x^2 + 16 + 8x -3x -12 -3 = 0 \\\\\sf\implies x^2+5x +1 = 0 [/tex]

Now let's use the Quadratic formula ,

Quadratic Formula :-

[tex]\qquad\boxed{\boxed{ \sf x =\dfrac{ -b \pm \sqrt{ b^2-4ac}}{2a} }} [/tex]

With respect to Standard form ax² + bx + c form. Here a = 1 , b = 5 and c = 1 .

[tex]\sf\implies x = \dfrac{ -5\pm \sqrt{ (5)^2-4(1)(1)}}{2(1)} \\\\\sf\implies x = \dfrac{ -5 \pm \sqrt{ 25 -4 } }{2} \\\\\sf\implies \boxed{\pink{\sf x = \dfrac{-5+\sqrt{21}}{2}, \dfrac{-5-\sqrt{21}}{2} }}[/tex]

A number squared is just the number times itself.

[tex]n(n)=n^2[/tex]

Answer:

A number squared is a number to the power of 2 or the number times itself.

Step-by-step explanation:

Lets say you have a 4 to the 2nd that would mean that the 4 is multiplied by 4. Dont get the exponent confused as the number to multiply it as. Look at [tex]9^{2}[/tex] for example, you would multiply the number 9 2 times not 9 times 2 so it would be 9x9.

Answer\Pattern for the right side will continue by 2 and the pattern on the other left side the pattern will continue by -2.

The solutions of the given equation are x=4 and x=-4. Therefore, options B and E are the correct answers.

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic equation is x²-16=0.

Here, x²=16

x=±√16

x=±4

So, the solutions are x=4 and x=-4.

Therefore, options B and E are the correct answers.
