Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
The expression 9+5 is equivalent.
It is: 8+7 = 15
17 2x4=8+(3x3)=17 3x3=9 9+8=17
5+6+36-4=43 * * * * * That is an equation, not an expression. An expression might be 5+6+36-4 or 43 but when you put the + sign (or <, > etc) it becomes an equation (or inequality).
3 + (8/4) = 5
-2( 3m + 9 ) =
the sum of 8 and -9, decreased by 2
8m
8
A numerical expression in math terms has numbers and operations like for an example 1. 4+9 2. (8-2)+5
8 over 27
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
5 plus 8
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
The expression 9+5 is equivalent.
24 x 8 + 2
