Answer:

length = 2x⁴ + 3x² - x

Step-by-step explanation:

  • Formula Needed:

A = lw

Where:

A = Area of the Rectangle

l = length

w = width

  • Given:

A = 14x⁵ + 21x³ - 7x²

l = 7x

w = ?

  • Solution:

Substitute values to the Formula:

A = lw

14x⁵ + 21x³ - 7x² = (7x) w

(14x⁵ + 21x³ - 7x²)/(7x) = [(7x) w]/(7x)

w = 2x⁴ + 3x² - x

Therefore, the length is 2x⁴ + 3x² - x
