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

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.
(x^2-14x+49)
The expression "20 49" represents a mixed number, which can be converted into a fraction. To do this, multiply the whole number (20) by the denominator (49) and add the numerator (0), resulting in 20 × 49 = 980. Therefore, the mixed number 20 49 can be expressed as the improper fraction 980/49.
The expression "y to the second power minus 49" can be written mathematically as ( y^2 - 49 ). This expression can be factored using the difference of squares, resulting in ( (y - 7)(y + 7) ). Thus, ( y^2 - 49 ) represents the product of two binomials: one that subtracts 7 from y and another that adds 7 to y.
It is an algebraic expression
- sqrt(49) = -7
