Because 3/5 and 5/3 make a product of 1, so you have one x on the right side.

Coefficients are added together because they are like terms, this can be proven with the distributive property. For example, x(2x+x)=2x^2+x^2=3x^2.

The commutative property of addition and the associative property demonstrate this.

The word "commutative" comes from "commute" or "move around", so the Commutative Property<span> is the one that refers to moving values around.

The associative property<span> states that you can add or multiply regardless of how the numbers are grouped. </span>

The length of a rectangle is 4 in longer than its width.
bija089 [108]

The area of the rectangle that has a perimeter of 44 in is calculated as: 117 in².

<h3>What is the Area and Perimeter of a Rectangle?</h3>

Area = length × width

Perimeter = 2(length + width).

Given the following:

  • Width = w in.
  • Length = w + 4 in
  • Perimeter of the rectangle = 44 in.

Therefore:

2(w + 4 + w) = 44

Solve for w

2(2w + 4) = 44

4w + 8 = 44

4w = 44 - 8

4w = 36

w = 9

Width of the rectangle = w = 9 in.

Length = w + 4 = 9 + 4 = 13 in.

Area of the rectangle = 13 × 9 = 117 in².
