Step-by-step explanation:

<h3>Given</h3>
  • Side 1: 3x² - 2x - 1
  • Side 2: 9x + 2x² - 3
  • Perimeter:  5x³ + 4x² - x - 3
<h3>Part A</h3>

Sum of side lengths 1 and 2

  • 3x² - 2x - 1 + 9x + 2x² - 3 =
  • 5x² + 7x - 4
<h3>Part B</h3>

The perimeter is the sum of all three sides.

<u>The length of the third side is</u>

  • P - (side 1 + side 2) =
  • 5x³ + 4x² - x - 3 - (5x² + 7x - 4) =
  • 5x³ + 4x² - x - 3 - 5x² - 7x + 4 =
  • 5x³ - x² - 8x + 1

Part A - addition

Part B - subtraction

2x^2 / x^2 - y^2 - x^2 / xy - y ^ 2​
Juliette [100K]

Answer:

2 - 2y^2 - x/y

Step-by-step explanation:

2x^2/x^2 = 2

and

x^2/xy = x/y

therefore

2x^2/x^2 - y^2 - x^2/xy - y^2

= 2 - y^2 - x/y - y^2

= 2 - y^2 - y^2 - x/y

= 2 - 2y^2 - x/y
