2(n + 10)
n+3 the sum of a number and three means a number plus three.
An expression that represents the sum of a number and 12 is ( x + 12 ), where ( x ) stands for the unknown number. This expression indicates that you take the value of ( x ) and add 12 to it.
The English expression for the quotient of nine and the sum of a number and one is "nine divided by the sum of a number and one." This can also be written mathematically as ( \frac{9}{x + 1} ), where ( x ) represents the number.
(6+n) n= a number
x + 5
n+3 the sum of a number and three means a number plus three.
An expression that represents the sum of a number and 12 is ( x + 12 ), where ( x ) stands for the unknown number. This expression indicates that you take the value of ( x ) and add 12 to it.
The English expression for the quotient of nine and the sum of a number and one is "nine divided by the sum of a number and one." This can also be written mathematically as ( \frac{9}{x + 1} ), where ( x ) represents the number.
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
(6+n) n= a number
6
10+n=
6+n
x + 5
X+3
n + 10
An algebraic expression representing the sum of a number squared and 2 can be written as ( x^2 + 2 ), where ( x ) is the variable representing the number. In this expression, ( x^2 ) indicates the number squared, and adding 2 accounts for the additional term.
