How do you write an expression with a variable?
You can write an expression with a variable in many different ways. First it all depends on what the word problem says. For Example : *Three times a number increased by four is less than eight. The answer would be 3x+4<8 or it could be written as 8>4+3x it will equal to the same amount. It doesn't matter what variable you use if it doesn't have an amount. Because all variables equal to 1, you can use any letter. REMEMBER EXPRESSION HAVE >,<, OR = . WHILE EQUATIONS HAVE ONLY = . Hope I helped (: . *Problem found by Fantastic Five #37 problem #2 2008 Revision Gunnells Publishing, LLC.
How do you factor the expression two m squared minus eight?
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)<-----

What is the expression for difference of 8 and a number?
n - 8 is the expression for the difference of eight and a number.'Number' is a variable, so the variable must be a letter (in this case, 'n'). 'The difference' is going to be the subtraction symbol that is in between the 'number' and eight, so it must be n - 8. It could, of course, be 8 - n.

Which of the following verbal expression represents the algebraic expression 2x-8?
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.

Eight more than twice a number?
The expression "eight more than twice a number" can be written as 2x + 8, where x represents the unknown number. This expression indicates that you should first multiply the number by 2 and then add 8 to the result. For example, if the number is 5, then 2(5) + 8 = 10 + 8 = 18.
