Answer:
192 cm
Step-by-step explanation:
Since none of the terms have the same variables the like terms would be (A) because they are both constants
Answer:
x=17
Hope it helps;)
Step-by-step explanation:
Subtract 8 from both sides of the equation
-x+8=9
-x+8-8=9-8
Simplify
Subtract the numbers
x= -17
Divide both sides of the equation by the same term
x= 17
-x/-1= -17/-1
Simplify
Cancel terms that are both in the numerator and denominator
Divide the numbers
x = 17
To evaluate this you need to multiply something
πr2 is an example of a (D) model.
<h3>What exactly is a model?</h3>
- A mathematical model is a system description that makes use of mathematical concepts and language.
- The process of developing a mathematical model is known as mathematical modeling.
- Natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences all use mathematical models (such as economics, psychology, sociology, and political science).
- The use of statistical equations to solve problems in business or military operations is a large part of the field of operations research.
- Mathematical models are used in music, linguistics, and philosophy (for example, intensively in analytic philosophy).
- A model is, for example, the πr2 method for calculating the area of a circle.
Therefore, πr2 is an example of a (D) model.
