The value of x in the right triangle using the Pythagorean theorem is 15 units

<h3>How to determine the value of x in the right triangle?</h3>

From the right triangle (see attachment), we have the following Pythagoras theorem

x² = 12² + 9²

Evaluate the exponents

x^2 = 144 + 81

Evaluate the sum

x^2= 225

Take the square root of both sides

x = ±15

The value of x cannot be negative.

So, we have:

x = 15

Hence, the value of x is 15 units

Which of the following best illustrates the relationship between entities and attributes
Lelechka [254]

A statement which best illustrates the relationship between entities and attributes is: B) the entity CUSTOMER with the attribute PURCHASE.

<h3>What is an entity relationship?</h3>

An entity relationship can be defined as a data model with the highest level of abstraction and it is typically designed and develop to avail designers or programmers (end users) an ability to use a graphical tool to examine structures rather than describe them by using text.

<h3>What is an attribute?</h3>

In Computer technology, an attribute can be defined as a unique characteristic or quality which primarily describes an entity in a software program.

In this context, we can infer and logically deduce that a statement which best illustrates or shows the relationship between entities and attributes is the entity "CUSTOMER" with the attribute "PURCHASE."

Which value of x makes the equation 0. 75(x + 20) = 2 + 0. 5(x - 2) true?
bija089 [108]

Answer:

-56

Explanation:

From the equation:

0.75(x + 20) = 2 + 0.5(x - 2)

Open brackets

0.75x + 15 = 2 + 0.5x - 1

Collect like terms

0.75x - 0.5x = 2 - 1 - 15

0.25x = - 14

Divide both sides by 0.25

x = -56
