Which expression is equivalent to 2 3 2x
How do you find equivalent expressions?
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What are 2 expressions are equal?
An equation is a mathematical statement that two expressions are equal. The solution of an equation is the value that when substituted for the variable makes the equation a true statement.
Does 2x 2 equal?
Because 2x squared is equivalent to 2x raised to the second power, we can use this rule of exponents to evaluate 2x squared.
What is an example of an equivalent expression?
Examples of Equivalent Expressions
3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6x2 + 12y + 6.
Which equation is equivalent to?
Is 2x and 2y like terms?
Summary. Like terms are terms that have exactly the same variable and power in them—whether that’s x, x3, y, or even no variable! … But 2x and 2y would not be like terms because they have different variables, x and y.
What is an equivalent numerical expression?
What is the equivalent to 7 12?
This means 712 is equivalent to 58. ¯¯¯¯33100 . When we have a fraction with a denominator of 100 , the numerator gives us the percent, since the word “percent” literally means per 100 . This means the fraction is 58.

How do you write expression?
To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
What is algebraic expression examples?
An algebraic expression is a mathematical phrase where variables and constants are combined using the operational (+, -, × & ÷) symbols. An algebraic symbol lacks the equal (=) sign. For example, 10x + 63 and 5x – 3 are examples of algebraic expressions. … For example, x is our variable in the expression: 10x + 63.
How do you do expressions equations?
How can we describe 3x 2 as an expression?
A coefficient is a number that is multiplied by a variable in a mathematical expression. … In the first term, 3x 2, 3 is being multiplied by the variable, so 3 is a coefficient. In the second term, 7x, 7 is being multiplied by the variable, so 7 is a coefficient.
What does an expression look like?
An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.
How do you differentiate expression from equation?
You can define a numerical expression as a group of numbers and variables with no equal sign. An equation is a group of numbers and variables that does include an equal sign.
