Asmall square of side 2x is cut from the corner of a rectangle with a width of 10 centimeters and length of 20 centimeters. write an expression in terms of x for the area of the remaining shape.

Find the area of the rectangle. You can find the area of a rectangle with the following formula:



w = width, and l = length.

Plug in your width and length:



The area of the rectangle is 200 square centimeters.

The area of a square is also given by width * length. Multiply the sides together:



The area of a square is 4x^2.

Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
