What are the three parts of an expression?
A mathematical expression is an expression that contains numbers, variables, symbols, and operators connected with addition, subtraction, multiplication, and division. Each mathematical expression has different parts. Three of these parts are terms, factors, and coefficients.
How many terms are in expression?
A Term is either a single number or a variable, or numbers and variables multiplied together. So, now we can say things like “that expression has only two terms”, or “the second term is a constant”, or even “are you sure the coefficient is really 4?”
What are terms in expression?
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
What is like terms in algebraic expression?
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.
Which expression is equivalent to Z +( z 6?
Hence the given expression z+ (z+6) is equivalent to the expression 2(z+3)
How do you find the like terms of an expression?
When we look at algebraic terms to find like terms, first we ignore the coefficients and only look if terms have the same variables with same exponents. Those terms which qualify this condition are called like terms. All the given four terms are like terms, because each of them have the same single variable ‘a’.
Which expressions are equivalent to 2 4f 2g choose 3 answers?
- Option (a) and (d) are correct .
- An equivalent expression to the given expression 2(4f + 2g) is 8f + 4g.
- and 4 (2f + g)
- Step-by-step explanation:
- Thus, an equivalent expression to the given expression 2(4f + 2g) is 8f + 4g and 4 (2f + g)
What is equivalent to J J 2k?
2jk is the same thing as 2 x j x k, while the original expression of j + j + 2k can only be simplified to 2j + 2k unless you know more information about the nature of the variables j and k.
Are 3x and like terms?
“Like terms” refers to individual terms that have the same variable in them. Also, the variable in any “like terms” is raised to the same power. For example: 3x and 10x are like terms (both have the variable x, raised to the 1st power).
What expression is equivalent to 4b?
Answer. the expression equal to 4b is 4×b. hope this may help you.
What must be included in an algebraic expression?
An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs. It’s only a phrase, not the whole sentence, so it doesn’t include an equal sign.
What are factors in a expression?
Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression. For example, the expression 7x(y+3) has three factors: 7 , x , and (y+3) .
