(16 + 4x)/2
2(4 + x)
Depending on the missing operational sign, that would be 2(x plus or minus 8)
3x + 2x - 8x + 2x = -x
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
-2x + 6 + 22 = -2x + 28
Do you mean like this: (x + 5)(2x + 7) If so, then it means you multiply.
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
Two linear expressions with a sum of -5x plus 4 are ( -5x + 4 ) and ( 4 - 5x).
It is: 2x(2x+11)
To simplify the expression (3x + 4(2x + 5)), first distribute the 4: [ 3x + 8x + 20 = 11x + 20. ] Now, simplify the second expression (6x + 5x + 5): [ 11x + 5. ] Since (11x + 20) is not equal to (11x + 5), Lauren is incorrect; the two expressions are not equivalent.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
Multiplication and addition.
It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
It is an expression.
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
It is equivalent to 4x^2 +8xy
