The area is measured in square units.
Area of square: 25y^2
Let the number be x and so the expression is 4x -3
The base area is 15 + (x + 2)/x2.
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.

40
Area of square: 25y^2
The expression of 20 times 20 can be written as ( 20 \times 20 ) or ( 20^2 ). When calculated, it equals 400. This expression represents the area of a square with each side measuring 20 units.
Let the number be x and so the expression is 4x -3
The base area is 15 + (x + 2)/x2.

x = (r + st)/r is the expression that represents x in the equation rx - st = r.
To write an expression that represents the area of a figure, first identify the shape of the figure (e.g., rectangle, triangle, circle). Then, use the appropriate formula for that shape: for a rectangle, use ( A = \text{length} \times \text{width} ); for a triangle, use ( A = \frac{1}{2} \times \text{base} \times \text{height} ); and for a circle, use ( A = \pi r^2 ), where ( r ) is the radius. Substitute any known measurements into the formula to create the specific area expression.
To create an area model for the expression (xy - 6x - 18 + 3y), first rearrange it into a more manageable form: (xy - 6x + 3y - 18). Next, factor the expression by grouping: (y(x + 3) - 6(x + 3)). This allows you to express it as ((x + 3)(y - 6)). The area model visually represents the product of these two binomials, where one rectangle represents (x + 3) and the other represents (y - 6).
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.
