What are expressions like 4(3 2) and 4(3) 4(2)?
Equivalent expressions
Are xx plus 3) and xx plus 6 plus xx equivalent expressions?
To determine if the expressions (xx + 3) and (xx + 6 + xx) are equivalent, we can simplify them. The second expression simplifies to (2xx + 6). Since (xx + 3) and (2xx + 6) are not the same, they are not equivalent expressions.
Which expressions are equivalent to 9x?
Expressions equivalent to (9x) include (3(3x)), (18 \cdot \frac{x}{2}), and (\frac{27x}{3}). Any expression that can be simplified to (9x) through multiplication or division by non-zero constants is also equivalent.
Which expressions are equivalent to 81x?
The expressions equivalent to (81x) include (9^2x) (since (81 = 9^2)), (3^4x) (since (81 = 3^4)), and (x \cdot 81). Additionally, (81 \cdot x) and (x \cdot 81) are also equivalent forms. All these expressions represent the same quantity.
Are the numeric expressions -3-(-9) and -9-3 equivalent?

Definition for Equivalent Expressions?
Equivalent ExpressionDefinition of Equivalent ExpressionTwo algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same.More about Equivalent ExpressionTo symbolize equivalent expressions an equality (=) sign is used.Examples of Equivalent Expression3(x + 3) and 3x + 9 are equivalent expressions, because the value of both the expressions remains same for any value of x. For instance, for x = 4, 3(x + 3) = 3(4 + 3) = 21 and 3(x + 9) = 3 × 4 + 9( x + 3) = 21.The expressions 6(x2 + y + 2) and 6x2 + 6y + 12 are equivalent expressions and can also be written as 6(x2 + y + 2) = 6x2 + 6y + 12.Solved Example on Equivalent ExpressionChoose an expression that is equivalent to the expression 2n + 7(3 + n).Choices:A. 9n + 21B. -9n + 21C. -9n - 21D. n + 21Correct Answer: ASolution:Step 1: 2n + 7(3 + n) [Original expression.]Step 2: = 2n + 7(3) + 7(n) [Use the distributive property.]Step 3: = 2n + 21 + 7n [Multiply.]Step 4: = 2n + 7n + 21 [Use the commutative property.]Step 5: = 9n + 21 [Combine like terms.]well....in a totally inataquitly way...theotorical...e=mc2

What is two algebraic expressions that have the same value are?
Two algebraic expressions that have the same value are called equivalent expressions. For example, (2(x + 3)) and (2x + 6) are equivalent because they simplify to the same value for any value of (x). This equivalence can be verified by substituting values for (x) or by simplifying the expressions.
