What pair of expressions are equivalent?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
How do you find an expression that is equivalent?
Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.
Which is the best description of the equivalency of the two expressions?
Which is the best description of the equivalency of the two expressions? They are equivalent because when , the two expressions have the same value.
What are examples of equivalent expressions?
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) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.
How do you know if two equations are equivalent?
To solve this, you need to find “x” for each equation. If “x” is the same for both equations, then they are equivalent. If “x” is different (i.e., the equations have different roots), then the equations are not equivalent.
What is the meaning of equivalent in maths?
In simple words we can say that two things or quantities are equal when they are exactly the same like ½ is equal to ½ but ½ is equivalent to 2/4 as they represent the same value. Equivalent Expressions. Two mathematical expressions are said to be equivalent if they yield the same result upon solving them.
Why do we use equivalent expressions?
Equivalent expressions are expressions that have the same value. Writing equivalent expressions can make them easier to work with and solve. For example, these two expressions are equivalent.
What is the equivalent number?
Equivalent numbers are numbers that have the same value. Each type of number, such as fractions, decimals, or square roots, can be equivalent to other numbers of their types, or to numbers of different types, as long as they have the same value.

The correct answer is B) 16.
How does Sal find equivalent expressions?
Sal finds equivalent expressions by combining like terms and using the distributive property.
Why do brackets and parentheses have to include the other one?
Brackets [] and Parentheses () both have to include the other one because you could see both. It also reminds us that division and multiplication are on the same level, so generally done left to right. Also, addition and subtraction are on the same level left to right.
