What is simplification?

To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.

Given equation

(n + 8) + (n − 12) =

n + 8 + n - 12

solving constant separately and variables separately,

2n - 4

the common factor of 2 and 4 is 2

2(n - 2)

Hence the simplified form of an equation is 2(n - 2).

An equilateral triangle with side lengths of 7 units is translated 3 units to the right. What is the length of one side of the triangle after the translation, in units? 3 units

Answers

Answer:

[tex]Sides= 7\ units[/tex]

Step-by-step explanation:

Given

[tex]Sides= 7\ units[/tex]

[tex]Translation = 3\ units[/tex] (to the right)

Required

Determine the length of one side after translation

It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length

This implies that, the length of the sides of the equilateral triangle remain unchanged.

Hence:

[tex]Sides= 7\ units[/tex]

Draw a model to help solve 5/6 + 1/4. write ur answer as a mixed number.

Answers

So first draw your model and add 5/6 + 1/4 and then write your answer as a mixed number

The required simplified solution of the given expression in the form of a mixed number is 1 1/12.

Given that,
To determine the solution of expression 5/6 + 1/4. in the form of a mixed number.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,

= 5 / 6 + 1 / 4
=   [ 5×4 + 1×6 ] / [6×4]
= 26 / 24
= 13 / 12
= 1  + 1 /12 or 1 1/12

Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on the number line

Answers

Answer:

When we have a quadratic equation:

a*x^2 + b*x + c = 0

There is something called the determinant, and this is:

D = b^2 - 4*a*c

If D < 0, then the we will have complex solutions.

In our case, we have

5*x^2 - 10*x + c = 0

Then the determinant is:

D = (-10)^2 - 4*5*c = 100 - 4*5*c

And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:

D = 0 = 100 - 4*5*c

    4*5*c = 100  

       20*c = 100

            c = 100/20 = 5

As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.

This means that c must be larger than 5 if we want to have complex solutions,

c > 5.
