twice a number n is 2n
plus 3 is + 3
→ twice a number n plus 3 is 2n + 3.
p+2d
Let the unknown number be x and so the expression is: 2x-3
2b
2z
|5n - 2n|
Let the number be x and so the expression is 4x -3
eight less than twice a number
2x+3
Let the number be x and so the expression is: 2x+3
The algebraic expression for three more than a number is: X + 3
p+2d
(x^2-14x+49)
This is an algebraic expression. It can be written as 3(2x + 4)
Let the unknown number be x and so the expression is: 2x-3
2n
2x-3=x+2 answer x=5
If the number is represented by variable x, then twice the number is represented by 2x.
