Answer:
Step-by-step explanation:
<u>We know that:</u>
- Perimeter of a rectangle = Sum of all its sides
- Length of rectangle = 4x² - x + 2
- Width of rectangle = 5x - 3
To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".
<u>Solution:</u>
- Perimeter of a rectangle = Sum of all its sides
- => 2[{4x² - x + 2} + {5x - 3}] = Perimeter
- => 2[4x² - x + 2 + 5x - 3] = Perimeter
- => 2[4x² + {-x + 5x} + {2 - 3}]
- => 2[4x² + 4x - 1]
- => 8x² + 8x - 2
Hence, the perimeter of the rectangle is 8x² + 8x - 2.
To solve the equation you can first subtract 4x from both sides. Then,
Since you arrive at something false, -5 is not equal to negative 8, so the equation has no solution.
