How do you write a polynomial that represents the area of the square?

How do you write a polynomial that represents the area of the square?

  1. Answer: The answer to your question is Area = 49n² – 70n + 25.
  2. Data. Length of the side = 7n – 5.
  3. Formula. Area of a square = side x side.
  4. 1.- Substitute values. Area = (7n – 5)(7n – 5)
  5. 2.- Expand. Area = 49n² – 35n – 35n + 25.
  6. 3.- Simplify. Area = 49n² – 70n + 25.
  7. 4.- The polynomial is 49n² – 70n + 25.

How do you write an algebraic expression in standard form?

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y).

What is a basic expression?

BASIC Expression: An expression can be variable or constant or combination of them. Operator: An operator is a symbol or sign that specifies the certain operation to be carried out with given data or operand. For example c= a + b, where ‘=’ and ‘+’ are operators. In above example a and b are operands.

How do you write a letter of interest for a school position?

How to write a letter of intent for teaching job

  2. Open with a summary.
  3. Outline your education.
  4. Highlight previous work experience.
  5. Describe your teaching style and values.
  6. Include a polite and optimistic closing.

Is a circle a polynomial?

Hence any rational parametrization x(t),y(t) of the circle has to have 2 poles (that is, x(t) has 2 poles and so does y(t)), so x(t),y(t) can’t be polynomials (as polynomials have only one pole, at t=∞).

What is area formula?

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

What tells you something is a formula?

A formula is a fact or rule that uses mathematical symbols. It will usually have: an equals sign (=) two or more variables (x, y, etc) that stand in for values we don’t know yet.

How do you write a letter to the school board?

Present Your Concerns Start by explaining the situation. Keep the letter short, ideally no more than a page, but make sure you include pertinent information. If you are writing about an incident, add names, times, and dates. Maintain a positive and respectful tone when detailing the situation.

How do you write an algebraic expression for an area?

Explanation: The formula for area (assuming this is a rectangle) is: A=l⋅w where A is the area of the rectangle, l is the length of the rectangle and w is the width of the rectangle.

What are the examples of expression?

The definition of an example of expression is a frequently used word or phrase or it is a way to convey your thoughts, feelings or emotions. An example of an expression is the phrase “a penny saved is a penny earned.” An example of an expression is a smile.

How do you find the perimeter and area of a shape?

The perimeter of a two-dimensional shape is the distance around the shape. It is found by adding up all the sides (as long as they are all the same unit). The area of a two-dimensional shape is found by counting the number of squares that cover the shape.

How do you solve area and perimeter?

Assuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.

What is a written expression?

What is it? Written expression refers to a highly complex, cognitive, self-directed process. Higher order components include planning, translating (drafting), reviewing and revising.
