9X + 7
It can be: 7x-11
An exponent.
" 3x + 5 " does.
It is 9*(n + 7)
9X + 7
It can be: 7x-11
An exponent.
Let the number be x and so the expression is 4x -3
" 3x + 5 " does.
3n + 4
7/ 3/
7n+5
This expression would be 3x-7.
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
5n + 16 ======
