Operations with Polynomials

Given this question, what would you do mathematically to find the area?

• (d+9) + (d-3) because the area of a rectangle is length + width

• (d+9)(d-3) because the area of a rectangle is length times width

• (d+9) /(d-3) because the area of a rectangle is length divided by width

• None of the above

Given this information how could one find the perimeter?

• (d+9)(d-3) because the perimeter of a rectangle is length times width

• (d+9) + (d-3) because the perimeter of a rectangle is length plus width

• (d+9) + (d+9) + (d-3) +(d-3) because the perimeter is when we add up all the side lengths and in a rectangle opposite sides are equal

• (d+9) (d+9) (d-3)(d-3) because the perimeter is when we multiply all side lengths and in a rectangle opposite sides are equal.

(2x+3)²

• Rewrite (2x+3)(2x+3) and use the box method

• Rewrite (2x+3) + (2x+3) and combine like terms

• multiply each term inside the parenthesis by 2

• none of the above

Simplify:
(x-7)²

• x²-49
• x²+49
• x²-14x+49
• x²-14x-49
