There are 4.
As an algebraic expression it is simply: 18-x
a variable minus a number and the same variable is b-6b= -5b
The expression is: 10-x
In order for this to be answered you will have to find the value of K. Then you will minus that by 22.
It is y - 12.
In the expression 5-4t it is t that is the variable
This is considered an expression "x^2 - 49", or alternatively a function of the variable x. In that sense, when you apply the expression to a certain input (such as x=3) you obtain a number (3^2-49 = -40).
It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
As an algebraic expression it is simply: 18-x
a variable minus a number and the same variable is b-6b= -5b
Your variable (a number) X, minus 100. X - 100
That is not a valid equation because the linear expression is not a polynomial. You can't have a variable in the denominator.
"An expression of three terms" means that the expression has three parts, combined by plus or minus signs. Within each of these parts (terms), there can be a single number or variable, or a product or division involving several other pieces.
Another rational expression.
The question contains an expression but not an equation. You cannot solve an expression.
Use a character variable. For example: plus = '+' minus = '-' You can now refer to these symbols using the variable names "plus" or "minus".
