Let the number be x and so the expression is 4x -3
16c^2-49 -> (4x-7)(4x+7)
x = (r + st)/r is the expression that represents x in the equation rx - st = r.

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.
(x^2-14x+49)
It is an algebraic expression
