4.6w - 3 + 6.4x - 1.9y <br> What are the terms and coefficients?
Soloha48 [4]

For the algebraic expression 4.6w - 3 + 6.4x - 1.9y, the terms are 4.6w, - 3, 6.4x, and - 1.9y, and the coefficients are 4.6, 6.4, and -1.9 respectively.

Given: To find terms and coefficients in 4.6w - 3 + 6.4x - 1.9y

What are algebraic expressions?

Algebraic expressions are sequences or combinations of characters containing letters, numbers, variables, symbols, operands, etc.

They help in making a big problem short and to make a relationship between different parts of the problem.

What are the terms?

In algebraic expressions, terms are individual components involved in forming the algebraic expression except for the operators.

What are coefficients?

In algebraic expressions, coefficients are the numbers of letters that are associated with the variables.

Let's solve the given problem:

Given algebraic expression: 4.6w - 3 + 6.4x - 1.9y

Therefore the terms in the algebraic expression are: 4.6w, - 3, 6.4x, and - 1.9y

and the coefficients are: 4.6, 6.4, and -1.9 as w, x, and y are the variables or unknowns of the given algebraic expression.

Hence for the algebraic expression 4.6w - 3 + 6.4x - 1.9y, the terms are 4.6w, - 3, 6.4x, and - 1.9y, and the coefficients are 4.6, 6.4, and -1.9 respectively.

AlladinOne [14]

A polygon is a closed figure formed by three or more straight lines called line segments.

<h3><u>Solution:</u></h3>

A polygon is a closed figure formed by three or more straight lines called line segments.

It is formed with only straight lines; if any curved line is used to form a closed figure than it will not be termed as a polygon

A polygon can be classified on the basis of a number of sides and measure of angles

Classified by Measuring the Angles:- Regular, irregular, concave , convex, quadrilateral and pentagon

On the basis of sides it can be a triangle having 3 sides, quadrilateral having 4 sides, pentagon having five sides and so on
