What expression has three terms and simplifies to 4x -7?
4x - 3 - 4 is one possible answer.
What is the constant of this expression 5-4x plus x-3?
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
What is the difference between an algebraic expression and an algebraic equation?
An algebraic expression doesn't have an equal sign (e.g. 4x+7) whereas an algebraic equation does (e.g. 4x+7=19). 4x=19-7 4x=12 x=12/4 x=3
Which expression represents 3 less than four times a?
Let the number be x and so the expression is 4x -3
How do you factor this expression completely 3x2 4x-15?
(3x - 5)(x + 3)
What is the cube expression of 4x?
3
If possible, factor each expression. 4x + 12?
A = 4x + 12 = 4x + 4 × 3 = 4(x + 3)
Which expression is equivalent to -3(4x-0.50)?
It is: -3(4x-0.50) = -12x+1.50 or as 1.50-12x
What expression has three terms and simplifies to 4x -7?
4x - 3 - 4 is one possible answer.
What is 4x plus 3 plus 2x?
4x plus 3 plus 2x is equivalent to expression 6x plus 3.
Explain why you cannot find a numerical value for the expression 4x - 5y for x equals 3?
You cannot because the expression still contains the unknown variable y.
What is the constant of this expression 5-4x plus x-3?
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
Is 4x plus 3(x-2) a expression or equation?

What is an equivalent expression to 4x plus 6?
2(2x + 3)
What is the best description of 5x3 - 4x plus 3?
It is a quadratic expression
What is the coefficient in the expression (3 x 5) plus 4x?
The 4.
How do you solve x-3 plus 4x?
Restate the question: Simplify: (x-3) + 4x(x-3) + 4x = x - 3 + 4x= x + 4x -3= 5x -3=======Answer 1:x - 3 + 4xThat expression is not an equation. It's just a number. The number dependson what the value of 'x' happens to be at the moment, and if 'x' changes, then(x - 3 + 4x) immediately changes. Without an equation, there's no "solution".Your expression would be an equation if there were an 'equals' sign ( = )anywhere in it.
