let x = a number

difference means that its subtraction

twice a number is 2x

so the equation should be

2x-5=3

add 5 to both sides

2x=8

divide both sides by 2

x=4

What type of triangle is formed by joining the points D(7, 3), E(8, 1), and

KiRa [710]

D(7, 3), E(8, 1), and F(4, -1)

We calculate the squared distances between the points:

$DE^2 = 1^2 + 2^2 = 5$

$EF^2=4^2+2^2=20$

$DF^2=3^2+4^2=25$

Since $DF^2=DE^2+EF^2$ we have a right triangle with hypotenuse DF.

Expand x(x – 4) Please answer!!! I will mark you as brainliest if you answer and its right!!

The expression x( x - 4 ) when expanded is x² - 4x

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.

When a bracket is expanded, each term is multiplied by the expression outside of the bracket.

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.

Consider the expression,

x( x - 4 )

Let us assume y = x( x - 4 )

Using the distributive property, a( b + c ) = ab + ac

y = x( x - 4 )

y = x · x - x · 4

y = x² - 4x

Therefore, x( x - 4 ) = x² - 4x

Therefore, the expression when expanded is x² - 4x.
